Cernbox on ubuntu 22.04

Hi,
I’m using kubuntu 22.04, and have installed cernbox from repo.2.10.1, but can’t seem to connect to my folders.
Upon launching, I get the connection wizard. First it request a server address, and I use https://cernbox.cern.ch. Then my usual cern id & pw. Then “Setup local folders”. One option is to sync /home, which the app thinks only contains 87 MB (it has GB of stuff in). But, ok, I select that, then get to the usual app homepage. No active connections are visible, and nothing syncs.
I can access my files no problem through the web interface, but would appreciate any help with the linux client.
thanks,
Gavin
