Issues Connecting to new sky router

Hi - we have V2 doorbell. We have just upgraded our router to a new sky one that is WPA2/WPA3. I get a “no internet” message on the ring app and when I try the step thru process to change the network but have found it doesnt help. The blue light spins and identifies the next step is to change wi-fi settings. I do not however get an option to connect to the temp Ring Network in order to do this. I do not have the tool to remove the fascia to press the reset button, but am able to disconnect the unit from the mains supply - hopefully the same result? (I have tried this but have got nowhere. I’m trying all of this via an android phone with “Intelligent Wifi” settings - all of which I have turned off. I have disabled “Connect to mobile data”. I have also turned off the VPN. I’m lost what to try now - HELP!
