Since some weeks almost every 5th Email I am sending fails. And the worst part: the app almost does not tell you when that happens. There is only a tiny message showing whether sending has worked or not. I often do not even wait for that message and just move on doing other things, so I don't see the message, as I expect sending email to just work. Even more frustrating when the email isn't even saved in drafts, so I have to do everything all over again. Please consider adding pushes for this

Sort out and fix the (now) confusing email account column that has stopped opening Inbox and folders directly under the active account and just stays at the bottom, looking like everything is shared in one place. Just as bad, is shifting the damn account you clicked so it jumps to the top. Stupid and confusing UI changes that are worse than before. Try testing it with several email accounts. I have loads for different reasons and you just made it harder to use.

The app used to work flawlessly until the last major update a couple days ago. Since then: no push notifications, sync problems, internal malfunctions. Re-installing the app and reconfiguring all necessary permissions and preferences (like background autostart, battery optimization) didn't change anything. This app is pretty much broken by now until the developers fix it. EDIT: Message to support from within the app gets REJECTED because of the automatically attached txt-file - ridiculous!
