Refresh token expires?

[Koniciuaaa]

Hello,

I get refresh token following this instruction:
https://github.com/ivanvermeyen/laravel-google-drive-demo/blob/master/README/2-getting-your-refresh-token.md

It works few days and after that it throws an error: "Daily Limit for Unauthenticated Use Exceeded. Continued use
requires signup"

I tested this few times and always the same. How is it possible?

First looks if your app isn't on test mode on google drive, second if you are using a long runing script, you needs refresh access token, example: masbug/flysystem-google-drive-ext#34
