Hi,
Just thought I would share this in case anyone else is banging their head against a wall.
I have been trying to delete a particular sharing label for ages. It’s not important so I haven’t really worried about it, but every now and then I try (and fail) …until today.
The notes say that an unused label will be deleted when the database is next optimised. That’s true.
I was convinced I had removed all instances of the label in question (filtering all my libraries by that label, selecting all and then removing it).
What I had forgotten was that, to share TV or* movies in a collection with a label, one needs to label the collection as well as the individual movies in the collection.
Removing labels from a lot of collections is a major faff (as you cannot filter collections), but that did fix it for me.
