Interesting bug. Just adding copper to a few of my suncatchers as they all use copper foil. On my phone as in the car. It will only let me have 14 tags not 15.
There is a character limit spread over all of the tags - could you have reached that so there aren’t enough left for the 15th tag?
No I had to delete two tags to add copper on three listings and tags deleted were longer
It was number of tags not characters. Can someone else try please. I am on Android.
I use my android tablet and can add 15
Can you remove one when you have 15 already and add another as I can’t. Have to remove 2 . Weird.
Just managed it with one. I think it doesn’t always recount after deleting one. Might need to do it as two separate actions . Still weird.
I use an android tablet and that does 15 no trouble.
I’ve identified the specific condition
If I only have 14 and add 1, all ok. The new tag is accepted and shows as such in the list when I tap it
If I have 15 and delete 1 to make space and then add a new 15th… No amount of ‘tapping’ will get it to show as accepted … but if I press update it does the add it.
The problem is that if I try to add a 16th or a duplicate it sits there in my list not showing as accepted in exactly the same way so I had, not surprisingly thought it was also rejecting my new 15th. It only therefore acts oddly if you try to delete 15, add a new 15. It does accept it if you press update but looks as if it isn’t accepting it.
Probably the same as the irritating bug, which says if you have 5 colours or materials and want to replace one you have to first delete one, press update then go back in to add the new 5th. An irrigation I have had come to accept
