Crashes all the time and unstable network connection – Themis Bar Review Review

This is really a pita. I have been continuously experiencing crash or freezing of the app and cannot continue my study. To solve the probelm I even needed to unintall, reboot, reinstall and log in to the app many times. Furthermore, I found that the app is having a hard time connecting to the internet once I switched between 4G and Wifi. When moving I need to disable my wifi, or the app will be very unstable.
