Delete all Data - Mobile Sync Stops Working

[kevinwestby]

I accidentally added ~50K images to one of my Lightroom Mobile collections in Lightroom Classic CC and it started syncing and killed my Mac performance.  I stopped it after realizing what I did, tried removing them from the collection, but they kept syncing.  So, I paused syncing, went in to Preferences and selected teh Delete all Data from the Lightroom CC options.....problem solved, so I thought.

I then tried restarting mobile sync, but now nothing will sync with Lightroom Classic CC.  New images are syncing between Lightroom on my iPad and iPhone and Lightroom CC....but nothing is syncing with Lightroom Classic CC now.

Any thoughts on how to resolve the issue?

Resolved by deleting Sync Data folder and restarting Lightroom (via Adobe Support directions)
