Clear cache

[raffaeler]

I am using v3.3.3 "Bluetooth Low Energy App" to examine the differences between an existing sensor and my own.
If I change the service UUID or the Characteristic UUID, nRF Connect still shows the old one even restarting the app or unplugging/plugging the nRF52840 Dongle.
I am not sure if the caching is done by the dongle or the app.

1. How can I manually delete the cache?
2. Can you add a specific button in the app to clear the cache?

Thanks for the great work!
