Revoke VPP App Assignment for Token

For those who stumble upon this thread looking for the same answer, I decided to do as stated and painfully remove the app assignments (all 100+) and then 'revoke all app licenses for the token'. I left it alone for about 6-hours and then when I checked an app the licenses were still allocated BUT I then did a manual sync of the token (as I noticed the last sync time was within my 6-hour window) and all the licenses were revoked - Total licenses = Available licenses, so happy days. I did not check the box to notify users as the devices are non-user affinity so, who knows what this option is for when taking it literally.

If anyone knows or would like to try it without unassigning all the app assignments, please let me know how you went!
