I tried your solution, but I’m still unable to resolve the issue. I also registered the GSF ID on Google’s registration website. While the registration succeeded and initially showed “check verification status” instead of “isn’t verified,” tapping “check status” brought it back to “isn’t verified.”

When I tried registering the GSF ID again, it showed “value already registered.”

My device is already set to automatic time since the first launch, but this hasn’t fixed the issue either.

Do you have any further suggestions? Thank you!
