Synchronise Renewals on existing subscriptions [closed]

Yes a solution for this is to manually change the date in “Next payment” field in the Billing schedule box on each subscription

A subscription can be unsynchronized by changing the next payment date to a day not aligned with the synchronization schedule. For example, changing a weekly subscription synchronized to Mondays to have the next payment processed on Wednesday will mean all future payments will be processed on Wednesday. This is because future payments are calculated based on the past payment and renewal synchronisation is only calculated and applied to the first payment.
