Error: App is blocked

[Karthick GM]

Hi,
Programmatically(using Php) we link the 'Google Console Project' with a 'Google Merchant Account' using Merchant API.
We got the refresh token while using our two gmail ids.
It return the below error,  log in with next another gmail id.

"This app is blocked
This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access."

Why this happens with recent gmail & not with previous ?

Thanks.
