Partly solved. I can test the in-app purchase item but see the following issues: The purchase data returned to the app show Auto-Renewable = false and yet that item in App Store Connect IS and Auto-Renewable item. Once "purchased", the item does not show up under subscriptions on the device for my tester apple ID. Is that a limitation on sandboxed Apple IDs? Any ideas on those issues? Thanks

For those devs using .Net Maui and running into release-mode compiling issues... After much fly-by-night analyzing and research compile issues, I found that if you add this to your .csproj file, you will eliminate compile-time introduced errors. <PropertyGroup Condition="'$(Configuration)|$(TargetFramework)|$(Platform)'=='Release|net9.0-ios|AnyCPU'"> <MtouchUseLlvm>True</MtouchUseLlvm> <MtouchLink>SdkOnly</MtouchLink> <UseInterpreter>true</UseInterpreter> <MtouchInterpreter>all</MtouchInterpreter> </PropertyGroup> Other issues are likely you code... So far, problem solved, app running well in release mode on all 3 platforms. Next hurdle - getting through the various app store approvals. Hope that helps a few devs here.
