Thank you for trying that. I have transferred this to a ticket so we can better investigate what is happening here as I can replicate that as well on your community.

Please apply the patch in ACP -> Support. This should hopefully resolve the remaining issue here.

This is due to your community is not running over HTTPS, please see this guide: https://invisioncommunity.com/4guides/advanced-options/configuration-options/using-ssl-https-r273/

Backup which we provide you is manual and in-the-moment. Whereas our scheduled ones are scheduled. In terms of data that is restored, there is no difference.
Not sure what you mean by "none in backup storage". As far as restoration issues, we test and execute our restoration strategy frequently. 
Daily, weekly, and we also have a complex manner to obtain point-in-time for anything which may be catastrophic, or daily/weekly is corrupt/otherwise unavailable in a unique situation.

The caching is not a bug which needs resolution, it is intended to aid customers with performance of the site for individuals who may not need to see a live version of your site. Keep in mind, it is not a rolling 15 min but rather 15 min since the guest hit the page that initiated the cache.  Unpopular pages, this likely won't even be an issue as you're describing but popular pages, most who want to contribute and stay up to date will login/register anyway, so we have found little in ways of feedback against this from our Cloud customers. However, if this is an issue, you're welcome to provide your suggestion in our Feedback forum.
 

Long as your records stay set, nameservers for root domains and CNAME records for subdomains on our Cloud, there’s no issue from our point of view. 

There are no cleanup tools really since version 3. Version 4 just hasn't had the need. When content gets deleted, the attachment(s) associated to it get deleted.

Check if you have an advertisement setup there which isn't rendering correctly. ACP -> System -> Advertisements. 

It looks like as your solution there is actually an embedded URL, this was stripped. I have submitted this internally for review.

The core applications available on self-hosted can be seen here: https://invisioncommunity.com/buy/self-hosted/
Then the Cloud offering is described here: https://invisioncommunity.com/buy
At the time of writing this, Courses is the only full application available to Cloud only. The rest are enhancements, sub-modules, or other features.

History.store is not from our software (or at least our core software, it could be something third party you installed).
You can find a list of our essential cookies below which cannot be rejected. The same list is on /cookies of your community as well.

You will want to enable “Trust IP addresses provided by proxies?” In ACP > System > Advanced Configuration 

As you changed your account's personal default stream, you will need to change that back to the Unread Content stream. To do this, you would want to go to the Unread Content stream: https://forum.casadodesenvolvedor.com.br/discover/unread and click Stream Options -> click "Set as your default stream".
As mentioned, it would be to remove the items from the All Activity stream.

I wouldn't worry about it then. Unless you need background tasks to run exactly, there's really no worry.
The background tasks run things like:
Publishing content Send out follow content digests Cleanup of items Update view counts etc...  

Everything is currently done from that rebuild. However, there were changes made afterwards which wouldn't reflect without another rebuild. I have moved this to a ticket to investigate why that message is still being shown.

Glad to hear that you got things resolved! Keep in mind that the system checks the URL for it to be 100% exact, down to the HTTPS and WWW (or non-www) so need to ensure you install at that exact same URL. 

The rebuilding option is to refresh the content from the Database record to the topic so that would not recreate the topic. I'm afraid, there is not currently a way to recreate the topics.

There is no need to. We automatically allow localhost when using your test key. Your test key is your license key appended with -TESTINSTALL

We have our Free Trial system which you can utilize to trial our products: https://invisioncommunity.com/clientarea/free-trial

Would recommend using the Alert system for this. It can be for all users, group(s), or member(s). 
 
 

Be sure to update your .htaccess as it sounds like you have URL rewrites in place. Can get the new one from ACP -> System -> Search Engine Optimization -> URL Rewrites' description.

Correct.
Please ensure that your account has the moderator permission to manage the sidebar in ACP -> Members -> Staff -> Moderators. Just because you're an administrator does not mean you have permission to manage the sidebar.

The software by default has video uploads disabled. You will need to enable them by editing your member groups and giving them this permission. It can by done by going to ACP -> Members -> Groups -> edit group -> Gallery -> Can upload movies?

I just wanted to ensure this as such. If you're intending to do this in all then you should be good to go. 
I always recommend doing a test to ensure you get what you want out of your search but other than that you should be all set. The system can handle large amount due to converting it to a background task. 

I'm afraid, there are no means to accomplish what you want in the core product here.
