When premium account uses a label on a shared activity, sometimes label doesn't appear for free account.
It's not clear the motivation.
The label on a shared task will never be created on the list of labels of other people, but should be seen in the shared task itself. You've said that it sometimes doesn't work, do you know when exactly does it not work? Can you reliably reproduce this issue and if so - what are the steps to trigger it?
excuse for the delay.
I have finished the work with a team with a free account.
I think the problem I had was due to the simultaneous presence of the same label on free account.
