An issue with the Google Tag Manager may require users to re-verify ownership of their site in Search Console.
There are numerous ways to verify your site – or property – within Google Search Console (GSC). One of them is via the Google Tag Manager (GTM).
Earlier this month, Google announced that it had detected an issue with the Google Tag Manager verification in Search Console.
We had an issue with the GTM verification method in Search Console, but it should be solved by now. You might need to re-verify. More details on how to verify at https://t.co/OkEwe4YvJv

The search giant did not provide any details on the issue, however, their announcement states it “should be resolved by now” and some users might need to re-verify their ownership.
Have you been affected? To find out if your site was affected, log in into GSC and try to access your site’s data. If you still have access then your site was unaffected by the bug. However, if you have been affected and need to be re-verified, Google will prompt the site owner to do so upon logging in into the Search Console.
Why should you care? If you used GTM for verification in Search Console, we advise you to double-check your properties in the Search Console to ensure they are still verified. If the properties are not verified, use one of the several methods to verify the property again.
