When a main account with Workspaces and Teammate features is downgraded to a plan that does not include them:
You won't be able to invite new teammates.
All existing workspaces, teammates, and their links are retained
Existing teammates can continue to view and manage links in their workspaces, according to their assigned role.
All functions will be limited to the feature availability or limits of the new plan.
For example, teammates may be able to edit existing links but not use advanced functions like redirecting links, tagging, deep links, etc.
