The new version has just been approved 🙂

I've uninstalled and reinstalled. So far, so good. When i got the above troubles, it was an upgrade froma previous version of your app.
I'll continue to monitor and if problems arive again, i'll let you know.

Improved content formatting in embeds is planned for future updates. We will consider better quote formatting too.
Bug with double notifications about new topics will be repaired in the next update.
Our team is currently investigating these issues. For now we recommend you reinstalling the app. Sorry for possible inconvenience.

The new update with a few bugfixes is now available 🙂

Have you upgraded to the latest version that includes "IPB 4.4 compatibility"? That should of fixed this issue.
No sorry the gateway itself is not included and Commerce integration isn't currently possible. I am working on a solution for more gateway support but it's still some months away.
Could you please PM me payment logs (acp > donations tab > payment logs) or admin cp login details to check? I want to confirm a few of these reports and then put together a quick patch for this.
Edit: Ignore that, I see you've already supplied further details. If you happen to have ftp login details for your ipb files, PM me and I can pass a test patch for you to try.
Edit2: Just wanted to apologies for everyone for the delay, I'm currently in the middle of a big move and only catching up with support now.
