Simple things don't work

Like saving a picture that is shared in a channel. Mark and edit selected text. Needs to refresh and re-login often. Does not feel like a stable app

Suddenly can’t send message

Out of the blue the return key on my iPad adds a new line instead of sending my message. It’s always been slow and buggy. I don’t understand why this app is so bad.

Not so great

App is very slow to open. Keyboard doesn’t always pop up when text field is tapped.
