@johnpoz Thanks for your ongoing support!
Not saying it's something wrong generally in 23.09 but at least something specific :-) Either in combination with my NTP server or something went wrong during the upgrade.
Went back to 23.05.01 and everything is OK again

After being back to 23.09 same as before...
The flag "u" and "s" appears randomly or changes after some time, currently it is set to "u":
