### 1/5 — Last update messed something up

*2022-11-26*

As of six days ago, the app is mostly useless. The update was supposed to improve stability and loading times, and both are now significantly worse. 75% of the time the app now gets stuck on the loading screen. About 15% of the time the app crashes after being stuck on the loading screen for several minutes. About 10% of the time, if you wait 5+ minutes the app will successfully load. 

Hopefully it gets fixed soon because the app is lot more convenient than going through the mobile website.
