It’s not memory pressure related.
iOS is killing the app because it doesn’t have access to the API that allows it to run in the background. That’s why it’s not listed in the Background App Refresh menu in the Settings app.
All API permissions are disabled by default on iOS. The developer must enable the API requests, and the user must accept them for the feature to be enabled.
iOS is probably killing the Voyager app when it’s in the background because whatever you’re switching to is using a lot of memory.
