It sounds like your mobile apps were syncing using the Gmail Dropbox account, and your desktop was using the business email.
As you won't be able to login to the Dropbox site using the old business email, you won't be able to access those files from there.
Since you changed the account on your computer, you might have a 'Dropbox (Old)' folder, which should have the files from the other business account. Could you do a search for that folder, or for a filename you are aware on on your machine to see if you can find it there.
Hi @Calaska, thanks for bringing this to our attention.
If the Dropbox site is only showing two devices, then that means the third device isn't connected to your account.
Which device is missing from the site?
This will help me to assist further!
As you mentioned that the Dropbox desktop application isn't showing the same files, then let's start there.
Is the app running in the menu bar near the clock? When you click the icon, what is the current sync status?
Is it signed into the same email address as that on the mobile app?
