Poly Lines missing on iPhone

Recently poly lines stopped working on iphone?
Both Chrome and Safari not working.

They were working fine and then they stopped recently.

They work fine on chrome on a MAC.

Hello,

There was a recent iOS update (15.7) which may have affected WebGL applications. Would you be able to provide the device info? Maybe screenshot the “About” page?

By the way, under the hood, Chrome is really using Safari as the browser on iPhone/iPad, so it’s unlikely you’ll see a difference between the two.

Thanks,
Gabby
