It didn't get installed to begin with, I dunno why tbh 😮💨
I've looked on google and found this: https://xdaforums.com/t/how-to-install-old-apps-in-android-14.4625641/ so if that's the issue, I'll try to increase the compatibility level to Android 7 and above, this might solve the issue. It's likely I'll fix either (or both) issues on R9, as R8 has already been built. However, if I am sure that either fix works (At the very least WebGL on phone since I can test it myself) I might push it to R8. I'll reply to this thread again once a solution to the issue has been found, thanks for letting me know!
