While using picture-in-picture video on iOS, and also cruising GitHub, GitHub will panic and stop fetching resources. It tends to work initially, but will eventually stop showing content and throw an error “Something went wrong: try again”. It used to throw a red error banner mentioning api calls but no longer does. This has been reproduced via Netflix and YouTube. Opening video > pushing to PiP by swiping home > open GitHub > search for a repository > start going through repo. Sometimes the error is immediate other times it will allow you to review code for a bit. Once it starts throwing the error, it generally continues indefinitely.
Currently on iOS 15.1.1
GitHub Mobile Version 1.44.0 (54346406)
