Lost data and shared data after revoking old phone

[burch driver 0]

I revoked my old mobile device because I upgraded my phone over a year ago. I did this in order to install the desktop version so I could copy and paste the data that was shared with me from another Evernote user into a desktop application. When I revoked my old mobile device that I haven't used for over a year All of the data that I've input in Evernote on my new mobile that I've used for over a year and all of the shared notes were lost, gone.

This may have happened - but in this case your new phone likely was never logged into your existing account. Just find out to which account it was connected, and the notes created on it will be there.

It is AFAIK impossible to loose notes that have been synced to the cloud server the way you just described.
