Ethereum.org background use - iPhone hacked?

So I was just looking at my iPhone last night, and saw the screen time widget was showing me basically full bar, as if my phone is being used constantly, every second of every hour. 24/7 that day. I check, and this goes back at least for Sunday, Saturday and Friday. Thursday showed normal use.

The app that it says is using all this screentime is Ethereum.org... which as far as I knew is not even open in a tab on a a browser in the background or anything. I'm not sure I've have visited the site until I got this news.

I contacted Apple and they suggested I add Ethereum.org to my blocked sites (which I have done, and the screentime usage has gone back to normal), or to clear cookies and caches for safari or chrome etc, which I may still do.

The thing that seems weirdest to me is that if some backdoor operation is in contact with and using my phone for whatever processes, that it's labeled out at ethereum.org... the actual legit Ethereum site, and not some other junk-hack url thats messing with my phone.

Have any of you guys seen this or experienced anything like this?

I have some Ethereum, and some bitcoin, through Coinbase, but none of that is affected. This seems like a completely separate thing, something sketchy maybe with the Ethereum site, or somebody else able to make it look like it ties back to the legit ethereum.org.

Thanks for your help!
