For the last week when I receive a group text from an apple Iphone, If I reply, it randomly sends my reply to only one of the group and then they reply to me, telling me they are the only one who got the my reply. When that one group member send that text reply it comes as a new text between me and that group member. So a whole new string starts. SUPER weird. I have been told there was an issue with an update on the Apple side but no confirmation yet.
