Hi there,
I have been trying to edit the tags on several listings for the last 2 days but it isn't working. I get the red pop-up on the top of my screen saying Etsy ran into an issue, and my tags are not changed. I cleared the cache, and tried 3 different browsers but still nothing. I read the previous discussions about this problem and it seems it goes back a few months ago, and Etsy doesn't seem to be working on a solution.
If the problem can not be solved just take down the button.
