Apple watch and 6GHz Wi-Fi (Wi-Fi 6E/7)

Hi!

I have an issue with my Apple Watch Ultra 2 when my iPhone 15Pro is connected to 6GHz Wi-Fi (Wi-Fi 6E/7). It seems like my watch does not get updates from the phone or the internet for example to update weather and other services. Notifications works though. I know the watch does not support 6GHz but only 2.4 & 5GHz and I also see that the watch is connected to a 5GHz network. I have tried to connect the iPhone to different kind of 6GHz networks, like Wi-Fi 6E/7 both with separated names for each bands, MLO-networks and bandsteering networks and the issue is all the same. When disconnect from Wi-Fi I get updates instantly, same if I move the iPhone to a 5GHz band. I run iOS 17.5.1 and watchOS 10.5. And the Wi-Fi routers I have tried are multiple TP-Link routers. I can provide more info if needed!
