Since switching to Rogers anytime I send a picture message to a non rogers/non iPhone contact it prompts them for a read receipt. This is extremely annoying! I have all of my settings turned off for read receipts and have been trying to figure this out for awhile and it seems that it is a Rogers issue. Any solutions?
I've noticed the same Read receipt message with my iPhone 7 too. It only pops up when I'm sending a picture/MMS message to a non-iPhone user.
I took a minute to review the options under Settings >> Messages and seems like the only Read Receipts option we get is for when an iPhone user sends a message. This makes me think this is an option set up on the receiver's end. Not yours. They could also have RCS messaging set up on their devices. As far as I know since this is still a fairly recent addition, it could also be another reason why you've just started receiving those messages now that you're with Rogers.
