Trying to MOVE a group or tag group to another DB silently fails

I’m reorganizing my dbs and trying to move a group to another db and it silently fails, whether I use drag/drop or Move To in the right-click menu.

I am able to move individual items from that same group, but can’t move the group.

And what’s reported in Window > Log?

Invalid encryption key and File still pending

FWIW, earlier this morning I noticed that DT3 still thought I was in trial mode, and I had to go delete an old activation in order to activate this one.

Pending files can’t be moved to other databases, they have to be downloaded first from the sync location (e.g. via File > Download Pending Files)
