Updated iOS now getting WebGL errors
-
@MetalAnon Hi, since the error appeared after updating the iOS version, and the version 18.7.2 (RC) is not a stable version, there is a high chance that something related to WebGL got messed up by Apple in that version. We cannot do much about it :/ We always recommend using stable OS versions to prevent these problems.

Have filed feedback (FB20873873) with Apple in relation to this issue. If possible I'd suggest others do the same.

I was afraid that’s where we end up. Thank you for checking that. I’ll see what I can do about filing bug with Apple and thank you to the other two participated in this thread much obliged. Have a good day.

Hey, I’m having trouble finding the proper page to post Apple feedback for this problem. You have a link to your feedback?? Thanks!

It is an Apple pre load app. I tried to share it here but it wouldn’t copy and I couldn’t find it in the App Store. Try this link https://feedbackassistant.apple.com/ -
Apple appears to have fixed the WebGL issue in a new build of 18.7.2 (22H124) which has now been publicly released.
NB you may need to reset iOS Beta Updates to Off to make the updated release visible

Still the same problem. Any suggestion except upgrade to iOS 26?

@schilpat same issues here. App does not load ANY layer data. iPhone 13Pro 256g. iOS 18.7.2 (22H123) Have set beta update to off then two fresh installs of app no help.

@nathan96753 Unfortunately iOS 18.7.2 (22H123) is the issue. Restart your phone and then check again for iOS updates (Settings / General / Software Update). If 18.7.2 is visible install it.
If you’re not offered the updated build 22H124 then this would point to an Apple release issue - file feedback with Apple.
