Why do I see different/missing links or features between my computers?
It is likely that you have authorized with odrive against a different authenticator.
For example, you logged in with Dropbox instead of Amazon.
Take a look at the “Authorized User” section in the odrive tray menu on each system and see if they differ?. If they do, deauthorize on the system that is showing unexpected content and then login with the same account you are using on the correct system(s).
