No maps shown on IPad

[Alessandro Di Mase]

On my iPad the app does not show any maps, just the grey background. Works fine on iPhone. I tried to restart, reinstall to no avail. Here is the error from the error console

@Alessandro-Di-Mase Hello, could you please provide any screenshots with this issue and also your version of iPadOS?

[Alessandro Di Mase]

@Suty it’s an iPad Pro 19.2 inch 6th generation running on iPadOS 18.7.2 (22H123). It always worked fine until a couple of days ago.

@Alessandro-Di-Mase Okay, I can't replicate this on the same device. May I ask from which region are you trying to access Windy?

[SimonUrbanek]

@Alessandro-Di-Mase I think, 18.7.2 is still RC version of the system and that cause this problem. See https://community.windy.com/topic/42388/updated-ios-now-getting-webgl-errors/7?_=1761906024873

@SimonUrbanek I have now upgraded to iOS26, the issue went away
