It seems to be a software change in iOS15 that is causing this as O2 don't support delivery texts and there is a conflict.
The only way to get an accurate delivery report is to precede your message with *0#
I have no affiliation whatsoever with O2 or any subsidiary companies. Comments posted are entirely of my own opinion. This is not Customer Service so we are unable to help with account specific issues.
