This seems to be a common problem at least amongst Galaxy products, since I have the same problem in Galaxy Tab A9 and S9, and also in S24 phone. In addition, there seems to be another thread about this specifically for Galaxy S23. So I guess it is a common Samsung android OS problem.
When I set Extended unlock using my location as a trusted place, and location service is always on, still every time the phone gets locked and I have to enter PIN to unlock.
I have updated the latest UI for all my products, One UI 6.x (Android 14).

I have read some "workarounds" like resetting this in Extended unlock, but it works only until next unlock, so it's not a workaround at all.

Please everybody, make an error report for Samsung in Settings->About->Contact us and create error report.
