Licensed accounts are automatically being change to basic accounts.

Hi, Kristi. 

That’s not much to go on in terms of troubleshooting. If you have a Business or Enterprise account, I highly recommend getting in touch with your Account Exec to figure out why this is happening.

If you’re on a Pro account, look to see if the number of available licenses is 0; possibly you had some annual licenses that didn’t renew.

Otherwise, please submit a support ticket to Zoom’s Billing team here and they should be able to assist you.
