Should the passkeys demo be working on Firefox Android

[tremby]

I'm trying to ascertain whether the various platforms I expect my users to be using have a good passkeys experience yet or not. But the support matrix is very difficult to parse for someone unfamiliar with the details.

When I try to use the demo on Firefox on Android I'm told there are no passkeys available. I also see an error briefly flash up and I don't know whether that's a clue or just jankiness of the test app.

Here's what I see:

The blacked out moment is just the phone's fingerprint challenge.

The error which briefly flashes up right after the blackout is hard to see but if you pause at just the right moment you can see it's "Your session has expired. Please log in again".

When I later tried to add more passkeys I got a different error:

So my question is: is this failure expected (just the current state of passkeys on Firefox on Android) or is this a bug in the demo, or an issue my end?
