Just to confirm, are you not seeing the thumbnail on mobile device or are you not able to change thumbnails from mobile device? Keep us posted.
Hmm, could you try signing out and signing back in to the account? Also, try uninstalling and reinstalling the app. Let us know if that helps clear things up.
