On iOS, we replace the embedded provisioning profile with a wildcard profile and resign the app. If you provide it, we will add auxiliary data to the application package before installation so the data will be present in your app’s sandbox. Resigning the iOS app results in the removal of certain entitlements. This includes App Group, Associated Domains, Game Center, HealthKit, HomeKit, Wireless Accessory Configuration, In-App Purchase, Inter-App Audio, Apple Pay, Push Notifications, and VPN Configuration & Control.
On Android, we resign the app. This may break functionality that depends on the app signature, such as the Google Maps Android API. It may also trigger anti-piracy and anti-tamper detection available from products such as DexGuard. For built-in tests, we may modify the manifest to include permissions required to capture and save screenshots.
