Read Receipts not working with last update

[Members_0gTVSlf]

We have AT&T as our mobile carrier. Three of us are on the same plan. Two have Samsung S21+ and the other is an older phone but ut is a Samsung. The two that have the S21+ cannot see each others read receipts but we can see it when we get texts from the older phone. Both S21+'s have it turned on. Please fix this issue with the S21+ update.

What messaging apps are being used on each phone? RCS may not work on Samsung Messages.

Also, RCS working is usually a carrier issue if the phone allows it.

Same with T-Mobile, typing and read receipts are not showing on Samsung Messages. I use Google Messages instead. Why don't you try using it as well, it's RCS works well
