Ratings and reviews

The app continuously fails to complete model downloads. The process consistently stops in the middle and resets back to 0%. I have tried multiple times without any success, which makes the app's main offline feature impossible to use right now. Please fix this download loop issue. Will update my rating once it's resolved.

It just keeps crashing.
