I want to add StartmonitoringSignificantLocationChanges in my app, but does it work in low power mode? Apple's documentation says that the background activity will turn off, does this apply to StartmonitoringSignificantLocationChanges?

I have wkwebview, from it the camera is triggered, a photo is taken and uploaded to the web. 
The problem is that when the photo is taken nothing happens on the web, the camera just closes and that's it, the button in webview that opens the camera stops triggering until you re-enter the application. Permishen to use the camera is added. 

If you open through safari - everything works, android also has the expected behavior, but in webview ais does not want to load. Maybe something new has appeared in webview that needs to be enabled, given permission? Tryedto allow inlinedmediaplayback, allowArbitryLoads
