I can never pinpoint what makes these prompts and problems show up constantly for some but almost never for me.
Are you behind CGNAT by any chance? I have my suspicions that CGNAT networks are more likely to trigger these robot detection flags than others (because their users share an external IP address with many others). I can imagine a website/user with only IPv4 set up ending up getting grouped together with the countless automated Chromium installs that may also ruin your IP address' reputation with spam prevention tools.
