After last update my Apple Watch no longer shows text messages as read after reading them on iPhone 11

The first (and simplest) thing to try if something isn’t working right is to restart your Apple Watch and its paired iPhone. If necessary (device not responding), try a forced restart. Both methods can be found here:

If that doesn't help, the next steps would be to unpair and pair your watch again and restore from the backup. This deletes all temp and corrupted files and re-indexes the file system.

I contacted Apple Support about this same thing about 6months ago and they said it's a known thing. It took me three different support guys (and three hours of my life I'll never get back) to finally get one who knew there was no fixing it. Apparently they took off the sync feature of text messages. They told me there was a way to request this changed back through some sort of customer request form, but I can't remember how to do that.

I tried this and I'm still having the same issues.
