When I delete emails, most of them don't actually get deleted. Next time I open the app, they are there in my inbox again! Same thing with emails I move into another folder. Next time I open the app, they are back in the inbox again. I like to keep my inbox clutter-free, so unfortunately this app is unusable for me until these bugs are fixed. UPDATE: I tried the app again after 4 years and this issue has still not been fixed. You still cannot permenantly delete emails in this app!
