After canceling the subscription from Stripe new subscription was created by M2 after the next payment was due.
There are two options for canceling a subscription through Stripe: Cancel - Immediately; or, Cancel - at End of Period.
I have selected the end of period option for several members for various reasons (from within Stripe).
Recently, the day of period end, the subscription canceled for a member.
The following day, however, a new subscription was created and a charge made to the member's card.
Through several emails with customer service, the latest reply indicates that it is how Stripe is integrated into the website.
