If I'm not mistaken, the two calls to handle() are reversed-- willConnectTo should have the one with connectionOptions.urlContexts and openURLContexts should have just urlContexts. Otherwise, this solved it for me.

A few relevant data points: -The sub option is $3/mo. and the lifetime is $50 -The new app is a bit more niche so I expect it not to sell as well, maybe half as well as the first app -After 12 months, I currently retain only 30% of subscribers with the first app. Although some of that could be people quitting subscription and paying for the lifetime. I also don't have a trial so it includes a lot of people subscribing for just a month
