I recently added few jira add-ons and now I can see some of them available to manage in
Jira settings > add-ons > manage add-ons
but few add-ons not shown here, instead they available with Jira subscription sections,
Jira settings > Billing > manage subscriptions
now my question is how its different? add-ons vs subscriptions.
is subscriptions only for billing? payment? or remove existing subscriptions?
