When I open to Appgyver PReview App and click on the app I am working on it flashes up one page of the app and the crashes a few seconds later.
What I was doing when this problem started was changing fonts.
I have tried the following:
- deleting and reinstalling preview app
- turning phone on and off
- using the debugger
Edit: Also, when I open the app in the web browser preview it says “An unexpected error has occurred”
