So I have a repeating group which I’d like to sort by the date it was modified, but only certain modification. So for instance, modifications on the group can include both something is added by the user, or it is liked by someone. I’d like to have the repeating group sorted by the the creation date of the thing added by the user to the group, and not the like added by the other.
I can’t use a specific field called modified, because the app is already live and in use, so if the thing is empty it would mess up the order.
Many thanks in advance!
