My wife has an SE2 iPhone running iOS 17.1.1.
She has the setting for sending “read receipts” in the Messages app turned off. But her friend on her Android phone demonstrated how she does receive a read receipt upon sending a text to her.
I have read in some postings in various other settings that this problem surfaced in iOS 15.
I take it there was never any resolution? Anybody else able to shed any light?
