Multiple declined payments on subscription service

I’m currently using Appstle Memberships for a monthly membership service I offer. I also offer a free trial for onboarding purposes for the first week. It seems about 95% of payments get declined when the first payment is due. I’ve had multiple members reach out on this issue, asking why payments aren’t being processed properly.

The error message I receive on the Appstle side is “Your card was declined”, this is coming from the payment gateway. I understand that some users use prepaid cards or gift cards for payment, those usually have the error “Your card has insufficient funds.” This is understandable, since we offer a free trial. However, it appears the “Your card was declined” error is coming from members who want to stay on with the service and have a legit card on file. I’ve also tested this with personal cards and had some of my friends try as well, receiving the same error and nothing from our banks.

Does anyone offer a similar membership/subscription service and has ran into a similar issue such as this? Wondering if this is a Shopify payment gateway issue or an issue with the Appstle app possibly? I’ve heard authorize.net might be a viable option.

This is putting a major damper on business :disappointed_face:

Let me know if any additional info is needed! Thank you!
