I have a missing term group in my tenant. It's not showing in the admin center where the term store is managed. So I found those very helpful PnP Cmdlets
With those I was able to determine that the term group actually still exists in the back-end.
I'm able to export it and the import throws the error:
Termset ID is already present in termstore.
Is there a way of getting this term group or term set re-imported?
Thanks for your help.
