That's my understanding too. Unless you've got the Exposure
Notifications things showing in your Settings, then I doubt it would
work - but I'd love to know for sure if anyone tests it on Lineage or
similar and what it does.

However, there are still problems like bluetooth really isn't designed
for distance measurement (amongst other fun, it will underestimate
distances outdoors which is the opposite of what's needed for covid)
and that seems to mean the app effectively uses a different definition
of "close contact" where being within "4m" of an infected person for
30mins will get you told to quarantine, leading to a false quarantine
rate of between 30 and 45% in tests. So I'm really unsure that this
app is a good thing, especially if people start taking it as gospel
that no alert means no problem and no need to take care.
