Creative Cloud IOS App Thumbnails not updating

[emilyt34819678]

My photo edits appear to be syncing perfectly across LR Classic, Lightroom, and Adobe PS LR.  I am having issues with the Creative Cloud IOS app.  Intiially, I thought the edits were not being synced to the Creative Cloud app, but later figured out they were....just the thumbnails are not updating.  When I export from the Creative Cloud app, the latest edit gets exported; however, the thumbnail is not update, so its impossible to tell what the photo looks like in that app.  

Any help would be greatly appreciated!!!!

Thanks.
