The installation of the /e/OS ROM e-0.13-q-20201119-UNOFFICIAL-mido was simple and uncomplicated as usual from @itsclarence.
My attention today was only focused on microG and the behaviour regarding exposure notifications.
As usual I installed the two reference COVID-19 Warn-Apps (GBR) NHS and (GER) RKI CWA.
Before and after installing the apps the microG status did not change: no display of the option ‘Exposure Notifications’. The two apps also show error messages.
The question remains: Why is the feature ‘Exposure Notifications’ not available for unofficial /e/ OS ROMs?
