In HTML5, what is a mouse click to iOS?

I chose to make apps for HTML5 hoping that it would be a way for my users (students) to access my content from any device using a browser. It works on a PC, it works on Android (Kindle and Phone), but it doesn't work on iOS.

It loads, but won't start. It won't start on load, or with a tap.

Why?

I looked into creating a version for iProducts, but the instructions I viewed for the exporter seem to be for testing the app on one device. I suppose that I would have to go through another process with Apple to distribute it.

I hate Apple. Their products are overpriced. Their genius is in their marketing. Unfortunately, NYC chose to give out iPads to students in need during the pandemic, so I am forced to develop with that in mind.

Here are the app links:

Thank you.

I read these forums for similar issues beforehand, and it appears that Apple is constantly switching things up and forcing Clickteam to adapt.

That's odd - it seems to work perfectly fine for me on iOS (iPhone) with the default safari browser. I am running an older version of iOS though (13.5)
