I’m just going to be that user today. I noticed that I’d somehow gotten signed into my account twice, so I selected the logout option in the profile tab. Now when I click on profile tab I get this screen and retry results in a white screen flash and a return to the posts tab. So right now I am unable to sign into an instance at all.

I am unable to cancel out of a comment. Tapping the Cancel link doesn't seem to do anything so I have to close the app and go back to try again.

Also, I don't see a way to reply to comments, I am only able to reply to the main post.

heheheheheh
