### 1/5 — Glitching

*2026-05-08*

The app continues to glitch it won’t talk and it keeps deleting his process. I purchased the subscription because others say it’s a great program I have yet to see that.

**Developer response:** We’re sorry to hear about your experience. The app should not be losing progress or having audio issues, and we understand how frustrating that is especially after subscribing. Please contact us through the in-app support or email us with your device model and app version so we can investigate and help fix this for you as quickly as possible. We truly appreciate your feedback and the chance to improve your experience.
