I’m not sure - sometimes it sticks, sometimes it does not. I tried it now again, closed the app after renaming the tag, and when I opened it again, it was back to the original form.
I’m attaching screenshots so that you can see what exactly I am doing.
+1 - I also have difficulty deleting and modifying tags. I’ll provide more detail later when I can access my laptop, but at this moment, I’m just posting to corroborate reports that this issue exists.
I was tagging my objects today over an hour and I had experienced a lot of bugs. Some tags indeed changed their names back after closing the set. A lot of bugs happens very occasionally like 2x per hour so there is no real trigger event to be able to reproduce it on the spot.
