Google Drive
Existing account not working
Please try to re-authenticate account or if that fails re-add Google Drive account and update FolderPairs to use newly added account. Some old API keys used by FolderSync can no longer be used, so adding a new account can unfortunately be required.
Browser authentication issue
If you have issues authenticating, please ensure Chrome browser is installed and it is the default browser. If issue persist try clearing data for Chrome browser in Android App settings. Firefox has also been reported by some users to work. Simple browsers on app store that use an internal standard WebView with not be able to work with the security measures Google is enforcing.

2. Click a folder or files to be added to another location. (it will be highlighted)
3. Press down "Shift + Z"
4. Choose a location in a dialog box.
"Quota exceeded" errors
Foldersync is registered and approved by Google to be able to access the Google Drive API, but it's subject to a quota on how many requests it can make per second across all users of the app.
This quota has been specially approved to be much higher than normal, but since so many users use Google Drive in FolderSync, the quota limit can still be hit, especially if you sync on the hour like 12.00, 13.00 and so on, since most users do this.
We're you to sync at random minutes on the hour like 12.17 you would be less likely to hit quota limit (currently quota errors only happen at around 0 minutes on the hour and only occasionally).
