create simply scene of camera, 2 objects and 1 material with texture.
if texture max size >= 1024 almost every time loading stops at 90% with error.
if set max size 34-64 = loading complete normal.

if try on iphone with ios 12 - all max size works fine.

unity 2019.2.0f1

This is an unfortunate bug in iOS WebKit that the Apple WebKit team is painfully aware of. iOS 13.0 and 13.1 are affected, 13.2 is to come out with a fix (although some have reported the iOS 13.2 fix to only be a partial resolution). Check out WebGL projects not loading after IOS13 update

webgl app with just one image is giving error on reloading the browser tab.
