I have just tested this on my end, and not seeing any issues with this. You would be best to report to the owner of that site if its not your site. If it is, of course let us know and provide an example we can take a look at.
They would get that prompt if they have clicked to register using twitter. The only other time that would be asked for is if they have physically clicked to link to twitter on their account in account settings. You would not see it, as you arent logging in using twitter. You are logging in using the internal login. In addition, it cannot ask you permissions to use their twitter account
As mentioned above, what you are describing is what you would see when a member is not allowed to use attachments for some reason. This may be permission to attached at all, or that they are over limits, meaning they also cannot attach anymore.
I would expect that to be the case, as its showing "my picks" there, and thats where you have an issue. We can work through this with you, but we are awaiting response from yourself on your ticket
I've moved this over to our suggestions area, but I just wanted to comment here to say your feedback is appreciated and welcomed. As this is a new way of working, we will indeed find better ways of working with people to ensure we provide you with the best possible service.
Incidentally, and just to add to my colleagues comments above, we do actually follow up these tickets also. They are internally marked so that we can come back to them and let people know once it is resolved. The feedback though is very much appreciated 🙂
