The mobile app is so bad, nearly nothing works the way it should. Tap a Notification, you‘re lucky if the right mail opens, try to attach images on iOS? For while it sent HEIV images instead of jpegs, so normal people were out of luck; hope it doesn‘t crash? It does. The UI is also pretty ugly.

But it‘s not only the app that is bad, the web client was quite functional for a while apart from the missing login persistence. Then came the new UI now it just kind of works. Try to move/tag many mails after each other? Now you also have to deal with clicking away success boxes as they start piling up and overlapping the very UI elements you are trying to reach. There are threads but for some reason they are way more cumbersome to use than GMail’s. Everything is gigantic now as well. I haven‘t checked yet but during the beta I could just not find some settings anymore. Hope they got added before launch.
