I can't ungroup objects. This option has been greyed out.
Is there another way?
Look at the objects in the Object Manager docker. That should tell you if the objects are grouped and whether or not they are locked.
I was able to move some text out from the group then the ungroup all option returned.
Now it just disappeared on me again!
I checked the Object Manager and is does say "Group of 12 Objects"
Don't see any lock beside it so I guess it is unlocked.
