hi Paul
yes, we have the same problem and are in contact with Citrix.
As you wrote, only container activated, everything looks good including startmenue, outlook and user search on Server 2019.
after enabling (local cache for container):
Folders below users look different, second logon startmenue is broken.
I have an open discussion below citrix-profilemgmt on slack.
what i see at documentation and is contradictory.
If you enable profile container, streaming is automatically disabled, at the end of the page, where "local caching is mentioned" you see that profile streaming can be activated to safe time?
best regards
Thorsten
