Hi @andrelam, I’m familiar with the functionality of microG GmsCore with Exposure Notifications API. I’ve demonstrated it several times in the near past here in the forum.
The crux is this: On my device with microG version GmsCore 0.2.13.203915 does not show the option ‘Exposure Notifications’, no matter if ‘OFF’ or ‘ON’. The brand new UK NHS Covid-19 app version 3.10 (100) 100 from 05.11.2020 can be installed but not used.
Please also compare with image #1 in posting obove.
