Changed package but no option to assign new packages to users

[7NArchitects]

We have recently cancelled our Zoom Workplace Business plus with UK/Ireland Unlimited and repurchased a Zoom Phone UK/Ireland Calling Plan only, to be used with the Zoom free meetings plan.

However under phone system management all our users are still showing up as being assigned Zoom Workplace Business Plus.

I made a change to one user’s profile (upgraded them to admin) and this has led to them having Zoom Workplace Business Plus automatically removed from their account and they are now showing up as being assigned Zoom Phone Basic, and have lost their Zoom phone functionality.

However I am unable to assign them a new calling package; the option for the new Zoom Phone UK Ireland Calling Plan is not available when I go to assign package - in fact there are no package options at all.

Can you advise?
