Oh, interesting, I stand corrected!

I was investigating this 5 months ago and the answer their slop machine gave was:

> Does Mollie retry failed payments (dunning) and track subscription states? Mollie does not currently provide automatic dunning or retry logic for failed subscription payments. Subscription states like active or past due are tracked, but you need to implement retry and notification logic in your system. This is a common feature request and may be on the roadmap, but no official release date is available.

From your link, note though:

> If your subscription payment does not succeed, Mollie may attempt it again up to 5 times (once a day), depending on the failure reason. After all retries have been exhausted, the subscription will be cancelled.

If there's a payment issue, I would not consider cancelling the subscription 5 days after the first failure as reasonable. I would expect the subscription to go into "past due" state, and to keep retrying.
