We have two pro licenses, but cannot assigned them to group users

Also are very disappointed by no live support! Why companies like Zoom are allow to charge a premium per month for online meeting services, and not provide support to customers. Might as well just use Google Meet! 

@dearasia2023 , 

The license assignment limit is based on the number of purchased licenses on your account.

Note: Sharing meeting licenses among multiple users is a violation of Zoom’s Terms of Service.

Resolution

You can purchase additional licenses on your account to increase the limit of license assignment. Once purchased, you can continue assigning licenses to users.

If you purchased additional licenses, but still receive the error message and are unable to assign the new licenses, contact Zoom Support.

Hi, @dearasia2023 

In order to ensure compliance with the license agreement, Zoom limits the number of license replacements that can be performed in a month.
Please note that if you exceed the limit, you will not be able to be granted a license for that month.
For example, if you have two licenses but exceed the number of times limit, it may happen that a paid license is granted to only one person.
As a remedy for operational errors, etc., it seems that when the month changes, the count of the number of replacements is reset and the paid license can be used again.
You have the option of waiting until September or, as @S_K said, purchasing additional new license
