I have several projects on Firebase and sent them to OAuth verification via Google Cloud. Some of them were sent on Oct/Nov 2023. No reply emails were sent back to me. I acknowledged that they have estimated the time for the review of the project 4-6 weeks. But they also said that first reply will be in 7 days. For now, 10 projects have no answer for more than 5-6 months. Does anyone know how to get a reply or verification process to be started?
I've tried to resend them for review by getting them back to testing and after this to production. Still no reply from them after 4-6 weeks. Some over projects were verified.
You need to file a support case with Google Cloud so that they can check your account and review your pending OAuth verifications.
