It is clearly an Apple issue that they need to resolve. This issue is not present in Safari or iOS (any browser).

I think it's an Apple problem. I cannot make it to work with any browser other than Safari. It works perfectly fine on Edge on iOS but Edge, Chrome, Firefox shows that error. It looks like that they have a Policy error and those scripts are not running on those browsers. Now, it's either they don't give a crap of other browsers and they developers are testing only on Safari, or they are working on it but very slowly... I tried with multiple laptops, using brand new browsers. Safari and iOS (all browsers) seem the only ones that work.
