I have just updated Android on the Onyx Boox Note, and am trying to reactivate the “Dropbox Sync” function on the device. This was working correctly before the upgrade.
Now when I go into Settings / Account / Dropbox Sync and click “Bind Account” I see the message:
Security Alert - another app on your phone may be trying to pose as the app you are currently using. The malicious app can’t access your account, but linking to Dropbox has been disabled as a precaution. Please contact support@dropbox.com
Any ideas?
