I was able to find and report the same item in the Shop app, within the “YZY” store.

Took a screenshot. Not happy about uploading a picture of a swastika, but wanted to capture it in case he backtracks.

I like your comment for the most part, but:

obviously comes from a mishearing by someone who didn’t read books

This is assumptive and prescriptive. The link I sent demonstrates that it’s been used extensively and for a long time by people who not only read books, but write books. I’m on board that “set foot” is the better phrase and likely to be the earlier one, but trying to dictate which is correct is - respectfully - a fool’s errand.

“Set foot” might be better established (and sound better), but “step foot” is not new.
