A quick heads up: Transmit 4 uses an old Dropbox API for syncing your favorites… and this API is now deprecated. That means, soon, Transmit 4 will no longer be able to sync your favorites using Dropbox.
The good news is that Transmit 5 will offer our (free!) Panic Sync service. The bad news is it’s not ready just yet. Almost! So close.
We apologize for our not-very-great timing. And we know “just buy our new thing!” is a pretty weak solution to a feature that got broken — we’ll do what we can to make it right for people impacted by this, once Transmit 5 ships.
