Unable to allocate our licence to a user

Hi @chris_smith., welcome to the Zoom Community!

Sorry to hear you’re receiving a message regarding a limit on license assignments when assigning Zoom One or Zoom Meeting licenses. This limit is based on the number of purchased licenses on your account. Once additional licenses are purchased, the limit will be increased, and you can continue assigning licenses to users.
 
Note: Sharing meeting licenses among multiple users is a violation of Zoom’s Terms of Service. Per section 1.2 Prohibition on Sharing:
 

You may not share an account, Host rights, or any other user rights with any other individual, unless otherwise expressly pre-approved by Zoom in writing. You may not share any login credentials or passwords regarding the foregoing with any other individual. You acknowledge that sharing of any such rights is strictly prohibited. Your right to use or access the Services and Software is personal to you and not assignable or transferable. You may not assign or transfer any account, Host rights, or any other user rights with any other individual, except upon (i) an individual termination of employment or relationship with their employer, as applicable, or (ii) Zoom’s prior express written approval.

 
If your use of Zoom services requires additional licenses to comply with Zoom’s single-user-per-license requirement, you can visit your Billing page on the Zoom web portal to purchase additional licenses.
 
Once additional licenses are purchased, the limit will be increased, and you’ll be able to assign licenses to users.
 
For more information, please refer to Zoom error code: “exceeded the limit of license assignment”.

I hope this helps!

I've had this same problem in our group for a few weeks now and get the same fatuous reply: renewed subscription, all users set to Basic, one message on screen says we have unassigned licences and immediately below it another says we have exceeded our allowance. Clearly a bug but cannot get a sensible reply from Zoom.

Same here and no useful response from Zoom support. 

And on another side I found this:

The license allocation has been changed to “each license can be reassigned up to 4 times/month”. For example, a customer who has purchased 20 Pro licenses will be alerted to purchase additional licenses if they change their license allocation 80 times in a month, even if they still have licenses available.
