I've updated the packaging configuration in the build settings to point to the Info.plist for "Any SDK" under release. This seems to have fixed the error with the app finding the types, but the entitlement error still persists and the ShareLink comes up but does not display any options for saving the file.

That seems like it could be it. The keys are not present in the Info.plist within the archived app package. Why would this happen? I cannot find anywhere else to set the keys for the type. Additionally, when I try to manually create the keys in the Custom iOS Target Properties, they are not saved and disappear if I reopen the project file.
