This app is alright. It randomly signs out for no reason and changing devices is a pain. My favorite is when you're trying to sign into a phone app, like Synology Photos, and the approval window appears over the number you need to match it with. so if you can't remember that number you have to back out and look at it again. A minor annoyance.

add Synology in the name: finding the app is always a mess because the name is super generic and the login screen doesn't even remind you of the name. or add push notifications: they were there but they have been broken for a long time

Signing into the app requires a code from the app no matter what I do. Password, still requires code. SMS, still requires code. Obviously I can't put in a code whilst I'm trying to sign in. Having had to reset my phone I have now lost access to this.
