I've been having issues on and off with the app over several months where I have to uninstall and reinstall the app on mobile to clear the constant "connecting" issue and even then it can result in the app being unusable for days because it won't log me into my account. Other issues are "bad network request" errors that will suddenly pop-up out of nowhere and make the app unusable or push notifications just not working. I've never had an issue with the desktop application.
