I am only using icloud private relay, country and time zone, no more local than that. But so is the mac, and I get at worst, a checkbox there, though I use Firefox there rather than safari, and extensions vary.

OK just checked. Safari on the mac requires just the one checkbox, but Firefox gives me the stop sign puzzle. Same relay.

Retrying on the phone, this time, the checkbox suffices. So there's apparently some history.

Since I am a scout's honor non-bot, I really am fed up with cloudflare and/or Google, or any other entity making me pay the price for someone else's bad behavior.

Thanks for asking.
