It's been a while ain't used this wallet but as I remember before when I was actively investing in altcoins, it seems I encountered the same as your problem.  So after their system updates this is what I did, I cleared the app data and cache can help solve an issue like this, or log out of your account and uninstall the app, reinstall, and log in again.  In that way, seems like you refreshing the app and your account, and their system will work well at your end.
