What you could try is make the marquees go more slowly. For every marquee, the speed setting can be set independently of desktop, tablet, and phone. When you edit a marquee by double-clicking on the marquee element in the gridder, you will see the marquee model. In here, you have a desktop button, a tablet button, and a phone button. When you click on the phone button, you can then change the speed to something slower, and that may fix it. But make sure to make the speed slower for all of the marquees that you have on your homepage for phone.
On my iphone, I couldn't replicate this.
This issue basically comes up if too much is being changed on the website rapidly. We had this issue sometimes when someone has a carousel with rapidly changing images on using autoplay, but I was able to fix this.
And we had this issue come up too when we had a lot of page overlays. I did some improvements, and hope this won't crash websites either.
This is the first time where I see that probably an issue like this happens because of the marquees.
Basically, since like two years Apple changed the browser and just made the browsers crash a website if a website takes too much computation power and does too many things at once.
