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"
