Notification ignores vibration settings

You can deactivate the vibration for a specific Notification Channel in androids app settings.
If you deactivate the vibration for the "Offline" Channel, the phone will still vibrate when an offline map is downloaded.

Start by tracing the offline map download notification and how the "Offline" notification channel handles vibration settings. Reproduce the issue with vibration disabled in Android app settings; done means downloading an offline map does not vibrate when that channel setting is disabled.
