I already purchased dropbox plugin for ipad, but sold it and bought new ipad air, do I have to purchase plug-ins again?

Hi Jeff,

If you are using the same iTunes account then you don't need to pay again. Simply open the app, touch the little 'gear' button on the main screen (Settings) and touch the 'Restore purchases' button. All plugins will then be restored and you will be able to use them again.

I hope this helps you! Let us know if you have other questions or comments.

Best,

Enrique
