Check seat usage
A downgrade is blocked when the target plan supports fewer accounts than the number of seats currently in use.
Check downgrade timing
payment-provider-managed downgrades can be subject to the configured minimum active period. If the account is not yet eligible, Send Listy blocks the change until the eligible date.
Check whether the plan is manual
A manual subscription does not use payment-provider self-service plan-change controls. Manual downgrades are submitted for administrator review.
Check account access
Paid plan operations require the correct signed-in Send Listy account and the current plan/subscription context.
