I restarted my Zwift subscription back in November, while I was primarily using Apple devices. I recently switched to a PC as primary Zwift machine. During a group ride today, I started getting “Your trial period will expire in 10 Km” message and when it finally counted down, I was taken to the billing page, and being forced/asked to switch to a different credit card (I guess Zwift wants me off iTunes so they can save on the App Store margins). As I was in the middle of the ride, I just clicked OK on everything so I can get back to it. So while the app still allowed me to finish the ride, I stopped collecting drops, and possibly experience. I estimate I lost out on 10,000 drops as a result, not to mention the disruption and causing anxiety during the middle of a workout.
I got a receipt from my Apple Card showing I was charged for the next month of Zwift. However, my Zwift profile shows billing will be switched a different card (Visa), via iTunes. Possible Apple Card bug?
