### 1/5 — App keeps crashing

*2025-05-23, version 1.1.5*

It crashes as soon as it opens, and my phone is up to date

### 1/5 — App Won’t Open

*2025-05-12, version 1.1.5*

I newly downloaded this app, and I expected it to perform decently, according to other reviews. I figured it might crash a little bit but would otherwise be okay. I was very wrong, as the app won’t even let me past two seconds on the first loading screen before it closes. The only function it’s able to perform before closing is asking for my microphone permissions. Please fix this issue, I hope to possibly use the app after it’s resolved. Thank you.
