5G works for me, but not if I have both SIM cards active, so one has to be turned off. (September update installed)
I have no problems with WLAN (otherwise try to go into the settings via the cogwheel that is next to the connected WLAN and change the MAC address type to Phone MAC).
Google Pay works. In the NFC settings at the top right, click on the 3 dots on Standard NFC method and select Android operating system.
