I have been struggled to login to Admob.
When I open the page, it showed a phone verification form.
I have been trying many times and waited for come back after months to retry but still failed to login.
This causing me unable to manage my mobile ads to put into my free Android apps on Play store.
I have contacted the support team and address my issue.
I am happy that the problem is now resolved. It just took me around 2 days.
