Thanks for the reminder; had trouble with this other week, and forgot what I had been inspired to do!
IN iOS, PRESS **RETURN** THEN SAVE TO SAVE NEW TAG!
Now if I could only figure out what scripture I un tagged in my other tag I was experimenting with edit to save tags (thinking I could change the name of the tag to the one that wasn’t saving). When I hit Cancel, I thought it would take me back to tags, but it removed the tag from the scripture.
