After authenticating your Google account, you can schedule reports to be delivered automatically to your Google Drive.
Better Reports can only access the files that you have specifically created or picked when configuring your schedules.
If you authenticated your Google Account before April 10th 2024, Better Reports technically has access to every file in your Google Drive.
In such case, Better Reports asks you to re-authenticate your Google Account.
Once re-authenticated, access becomes restricted to files that you have specifically created or picked when configuring your schedules.
