The only “difference” I have with the switch is -

I now get multiple ads all over the place on this site.

I was lucky - I never had a single ad in the past. I should clarify I’m in Australia.

What are the tracking pixels like on this site. I noticed the ads related to external sites I was browsing when I wasn’t even on PC but when I came back to PC it was advertising their product/service.

Edited to add it doesn’t matter if I’m on my iPhone XR or Mac. It’s the same result.
