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.

This is generally a good app. On some emails the text is really small and you have to zoom in. it's when there are long footers. I often send an email and find it's stuck in my drafts folder. Sometimes the app needs closing and reopening to get it to do things like opening an email. I was hoping the recent update has solved the problems with this app but it seems to be as unreliable as ever. Constantly need to close and reopen.

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!
