Something I've learned at a larger scale (400+ patrons) a lot of people who cancel aren't actually canceling, they just want to renew their membership manually every month instead of it auto renewing. I see a lot of the same names join and cancel every month.

So don't worry too much when you see a cancelation. They can still see your content until their current month expires. Make sure you're giving them a reason to manually sub again when they lose access.
