Hi, I think there is a bug in latest Mac OS (Catalina), in City of London or Canary Wharf, there is many WiFi signals in one place, often 100. The iPhone does not appear on the list, it is often connected anyway, but the "linked" icon does not appear... as I said, this is only when many WiFi in area.

Thanks for the additional info. Unfortunately, I have no way to test your findings. Hopefully, someone else experiencing the same issue will chime in and offer you a potential solution that they found worked for them.
Regardless, I suggest that you submit this directly to Apple here: Product Feedback - Apple
Are you trying to use your iPhone to provide a Wi-Fi network connection, via a Personal Hotspot, for your Mac to gain Internet access?

Yes. When there is very many WiFi spots, it doesn't appear on the list; and it doesn't appear as if I am connected, even though I am.... shame an iPhone hotspot appears randomly on the list, I feel like it should appear at the top of the list.
Other times works fine.
