Microsoft Teams Read Receipts Doesn't Work

This issue has resurfaced once again. I can confirm that the tenet admin has set the policy to user choice. However, even both people both have read receipts turn on (checked it today), receipts no longer appear. This affects collaboration, as you cannot be sure that people are even seeing what you have written, so you must guess. Looking at read receipts lets me know who I need to chase down, as not all messages need a reply, as I use the read receipts as a confirmation in some instances. Don't give people an option that they think is turned on, only for it to be disabled globally.
