Description

Hi, currently testing out model viewer on older devices and came across a TypeError while visiting modelviewer.dev. None of the models are showing up in mobile Safari on iOS 13.6 and getting this in the console TypeError: function is not a constructor (evaluating 'super(...arguments)') I'm currently using iOS Simulator on XCode 13.3 to produce the error.

We only officially support (i.e. run our automated tests on) the last two versions of iOS, which are currently 14 and 15. They have enough WebGL bugs to work around as is, we just can't support all of their legacy.

@brianyuen Have you been able to found a solution for this error?

[elalish]

Are you also testing on iOS 13? That version is not supported.
