Since Apple recently released IOS 13.5.1, I can see one issue running Cesium in IOS Safari
The issue is on the “Animation” widget. After loading a webpage embeding Cesium or SandCastle demos, the animation widget is just partially drew. I guest one part of the code missing executed after a js line failed somewhere
Here a picture showing the widget partially constructed
Not seen other issues for the moment using Cesium 1.69
Thanks for reporting this. Are there any console errors in the page when this happens? Does this consistently happen when you refresh or only sometimes?
I was able to connect my Mac machine to my iPad to monitor SAFARI using Web inspector and look at Console messages
Unfortunately no error messages displayed in the console
When browsing the CesiumJS web page and displaying the Cesium container, I can see the same issue
This issue only happens on iOS 13.5.1. All perfect in Safari on Mac OS
