I haven't yet logged a ticket with Meraki regarding this but we're experiencing the same issue.
Nothing has changed on our setup lately and it was working last on the 10th January when I set up my last batch of laptops. Only thing that's changed in the interrim are maybe a few windows updates.
Tried to use the "Send enrollment link" method as well but the web page just spins indefinitely at "waiting for device to check in".
Occurs for us on Windows 10 and 11 devices with Google Auth.
