The app was not correctly configured and cannot access your Dropbox

Hi @jsc41, @Robertosky, and @Glenn_Bloke:

It sounds like there might be a few issues at play here. Dropbox free accounts are limited to 3 devices as of recently, and when we were investigating this a few days ago, having 3 devices currently authorized to your Dropbox account before opening 1Password and attempting to link your Dropbox account caused issues.

Please try this set of steps for me and let me know if you're still running into issues.

1. Delete the Dropbox app from your phone.
2. Go to the Dropbox website and disconnect the 1Password for Android app: Settings > Connected Apps > 1Password for Android > Disconnect
3. Ensure that there's a spare device slot in your Dropbox account if you are using a free account: Settings > Security > Devices
4. Re-open 1Password for Android, relink your Dropbox account using your web browser.
5. If tapping allow to authorize didn't reopen 1Password for Android with your vaults connected, switch back to 1Password for Android and the file picker should be available then.

We're still investigating and hope to know more soon.

Jack
