This has just happened to me now. I didn't want to scare away users with an automatically billable free trial so I implemented my own way and they rejected it with this reason:"We noticed that your app offers a free trial without implementing the offer in App Store Connect. Offering free trials through App Store Connect ensures that when the free trial period is over, the user will automatically be billed (unless the user has cancelled the subscription).Next StepsTo resolve this issue, please use App Store Connect to implement free trials."My app has a lite version and a pro version. Users try the pro version for 2 months before switching back to the lite version if they don't subscribe.How did your appeal work? Did you have to give in?
