“Error Selecting Storage Location” (or “Invalid_access_token” With Dropbox) When Unlocking Database

Sometimes your security token or session expires on a third party storage provider like Dropbox or Google Drive. Usually this is seamlessly renewed but it can happen sometimes that this goes wrong.

To fix this you need to clear your (Dropbox/Google Drive/OneDrive) session. You can do that by:

On iPhone/iPad

1. Open Settings (tap the gear icon in the top right, above the list of databases)
2. Tap Advanced (at the bottom of the page)
3. Tap Manage 3rd Party Sessions
4. Tap to clear the session for your cloud provider of choice and confirm
5. Tap Done (in the top right of the screen)
6. Tap on your database
7. Enter your login details to re-authenticate

On Mac

1. Click File (in the menu bar)
2. Go to Cloud Drive Sessions
3. Click to clear the session for your cloud provider of choice
4. Go back to the Database Manager window
5. Double-click on your database
6. Enter your login details to re-authenticate

Now when you tap on your database to unlock you’ll be taken through the re-authorization sequence and your session will be renewed.
