For some time now I'm unable to give any new OAuth authorization in Google Apps Scripts from my Google Account for a scope that is outside the file I'm working from (.currentonly works, everything else doesn't).
It asks for a Google account I want to use and after selecting the account it shows:
This app is blocked
This app tried to access sensitive info in your Google Account. To keep your account safe, Google blocked this access.
See screenshot:
The screen with the requested permissions overview is not even shown. This happens for every new or old Spreadsheet file I try to add the permissions to. But Spreadsheets that already got the OAth before this stopped working are regularly updated with project triggers.
Here is my manifest file:
{
"timeZone": "Europe/Paris",
"dependencies": {
},
"exceptionLogging": "STACKDRIVER",
"oauthScopes": [
"https://www.googleapis.com/auth/spreadsheets.currentonly", // this works
"https://www.googleapis.com/auth/drive", // this doesn't work
"https://www.googleapis.com/auth/spreadsheets" // this also doesn't work
],
"runtimeVersion": "V8"
}
Everything works when I try to do the same from a different Google account. Because of this I think it has something to do with the whole Google account settings.
I tried enabling Less secure app access but it didn't help. 
Is is possible that the access from unverified 3rd-party apps is disabled in that account? How can I enable it again?
