Mine is fixed as well! Hopefully yours will resolve soon Bvledford.

Yep this is exactly what I have going on as well. Can't enable Find My on my Macs regardless of beta, etc. I do have an open ticket with "more than 10" as well. Hopefully they fix it soon. Thanks for posting this and keeping everyone else updated!

Have they resolved it yet? I submitted a bug in Feedback Assistant and am attempting to have Apple Support look into it for me since it affects non-beta devices also.

I am having this exact issue. Submitted a bug report as well.
