@JessRighe in-order to manage users to assign those licenses per @Vinnie reply; on the account as an Owner or Admin with permissions; the account will need to be one of the following:
Free with Credit Card, Pro, Business, Education, or Enterprise account
If you have not entered your information from the https://zoom.us/billing/payment; there is no payment method associated with the account; thus, you will be unable to assign licenses without an actual license or purchase a license on the account until that is setup - as stated in the Knowledge base article above (manage users)
Here are additional resources as well for resolving that issue:
Thanks @RN52_2 I updated the info and I can see the users now but @Vinnie when I click the user there's no option for license, only base. Also, when I check the payment history it doesn't show anything, as if I never paid.
@Vinnie@RN52_2 I spoke to the bank and the payment was confirmed. How can I check with zoom if they received the payment or get a proof of the payment?
