Can't add users to a parent plan

From the user management, I can't add users to the parent plan if it is set to be selected by default
I can just select one of the child plans, the parent has just a green flag icon and can't be selected, saying "Lifetime Subscription Active", but the user isn't listed in the parent plan's subscribers


I have 3 plans
- Free: parent, selected by default, exclusive
- - Individual: child
- - Company: child


This means that as administrator I can't manually add users to my free plan
How can I set the configuration to manage this issue?

Sounds like it's a free lifetime plan, but free lifetime plans aren't configured to create subscriptions. Within CBSubs > Settings > Global set "Create Subscriptions also for free lifetime plans" to "Yes" and retry.

Thanks, now I can add users to the free plan...still I don't really understand the reason for this configuration

It's because you can't override the hidden free lifetime plan with your own. There's currently no functionality for specifying a fallback plan. We've a feature ticket to implement functionality for this though. Your alternative is to have something like the below.

Plan 1 - Free, Lifetime, Exclusive
Plan 2 (Individual) - Paid, Exclusive
Plan 3 (Company) - Paid, Exclusive

Then you'd use the below usages in CB Auto Actions to subscribe them to the free plan when Plan 2 or Plan 3 expires. This would avoid needing to use parent/child structure at least.

Plan Active
