iMessage Read Receipts not working

Your activation of Read Receipts does not enable you to see anything. If you turn on Read Receipts, people that you send messages to will see that you have read it. For you to see a Read Receipt, the person that you have sent a message to needs to have turned it on. Are you sure they have Read Receipts turned on? Have you received notice from someone that you sent a message to that they read a message and you do not see a notice?

I have the same problem as the OP. I even tested this between my iPhone on 13.5 and my wife's phone on 13.4.1. I can't see if my messages to her are "read", only "delivered". However everything works just fine on her phone like when I read her messages.

Something is definitely wrong here on iOS 13.5 and it's not an SMS issue.

I would say this is not a wide spread problem, since there has not been a lot of talk. I also have my iPhone and iPad working on iOS 13.5 and both are getting Read Receipts since I updated.

Try going to Settings>General>Reset>Reset Network Settings, the power the device off and back on again and then test your iMessage. See if receipts are received after that. Resetting Network Settings will also remove all of your wi-fi passwords as well, so you will have to enter them again.

That would appear that you are speaking about SMS, not iMessage. You cannot get read receipts for SMS, iOS does not support that. All you will get is delivered.
