crane is only isolating your keychain and app data which is fine for basic stuff but it doesn't change your actual hardware fingerprint. instagram can still see the exact same device specs, GPU, screen resolution and sensor data across all those containers. if you run more than a few accounts they will definitely get linked eventually because the device profile is identical. you really need a proper device spoofer or at least some decent mobile proxies to stagger the connection footprint otherwise you are just wasting time.
