(Catalina) App Store purchases not shown
I have an upgrade of Mojave to Catalina.
It was a fresh Mojave installation w/o AppleID.
Then i upgraded to Catalina.
Now it doesn't show my purchases in the Appstore.
The trick with a new user and login to Appstore didn't work.
Familysharing is on.
On my other Mac with Mojave it is OK, also on my MacBook with Catalina.
I also had a fresh installation of Cataline on this new iMac and it was OK.
Any hints?
