iPad iPad SMS Messages wont sync "read"

[sonicrobby]

So I have my SMS forwarding on my iphone to my iPad. They come up just fine. However, when I read SMS messages on my phone, the iPad still has them on unread until I open them from my iPad. Whyyyyy? Ive turned iMessages off, restarted, turned back on on both devices, but still does it. I do have the iPhone 11 Pro with dual sim, could that be causing an issue? Both are on the latest version of the OS. For reference, its an iPad Pro 11"

Exact same issue, using iOS 13 beta

I've had the same issue between my phone and watch for a few weeks now. Certain group texts come through fine on the watch but others have broken out into individual texts. Tried deleting/re-adding the group and the same issue persists.
