### 1/5 — Bugged, don’t download.

*2023-11-27*

Once it’s downloaded it doesn’t show up in the App Library. Only way to delete it is to search it, add it to the homescreen, then delete it from there. It also disabled all my wireless communication. Put my phone in SOS mode until I enabled and disabled airplane mode.
