iOS 13.3. + MarkII suspend freeze

iOS update to 13.3.1 has made the structure sensor work unwanted way. From version 13.3 onward suspending an app for 4-10 seconds while sensor is attached and returning to the app will freeze the app. I’ve tested this with 11.2 SDK’s Scanner app.

By looking at wireless log it looks like that the structure is rebooting itself when the app is being long enough in the background (but not long enough that the iOS would close the app).
Structure Sensor disconnected!
Notifying app of state: Booting
Calling StructureCoreClient_Init!

Any idea how to prevent this booting? I can’t just detach the scanner every time I suspend an scanner app.
