Thank you @DKE_Watson and @Jen_Wrench!!
I came across another other post, titled included here in case someone else experiences the same issue and stumbles across this post while looking for a solution: ‘“Free Trial Expired” ~17km in to Ven Top. Paying member for over a year’ (The forum forbids posting links.)
I logged out and logged back in. I did not have any issues this morning. Woohoo!
Even if we can address the issue ourselves, I still think we should contact Zwift. Plenty of people use Apple App Store to manage their Zwift subscriptions and have been for years. It seems bit absurd that Zwift and Apple cannot sort this out and end up causing headaches among us subscribers.
