At least now you know it's broken.
You just have to fart around with it as in I don't even know what I did aside from poking it a dozen times then scrolled and saw where there were some options, one of which was, "add to home screen." I'm not sure whether it mattered to use Safari or...
I futzed around and figured out how to just avoid that and add to homescreen so it's there now. Thanks! :wee
On iPad, it sort of looks like it does on the phone in app format but no app, so I just made it a Tab. That's no biggy there.!
I have Chrome and tried there first and got that pop-up about a video, then went to Safari and got the pop-up about a video too. It's an iPhone 15. I use PC but when out of town, I can just navigate on the web on my phone as I guess it's just not meant for my phone lol.
