Element X has a few notification issues on Android (I use it daily): you don't get quick reply (which can be fixed by adding conversation shortcuts in Android), and you get a notification for every single message. Element X doesn't stack up the notifications, so if someone floods you 20 lines of text in less than 10 seconds, your phone will vibrate 20 times in under 10 seconds. It's quite annoying.
