鈿狅笍 Update:
Verified format: [user]'s [app name] on device
e.g. "Jonathan's Firefox Preview on Pixel 2"
This seems to be a regression from https://github.com/mozilla-mobile/fenix/issues/3317.

Was this default specced out somewhere? It looks like it was a regression w #3317 we just need confirmation of what it should be and then it's just changing the default :)
Yes, here: https://mozilla.invisionapp.com/share/QSR2F8UD4PN#/screens/357470305
The format there is '[app name] on [person]'s [device]' but this was scoped to match desktop which is the format currently used everywhere, i.e. '[app name]' or '[app name] on [device]' .
I think device name should include both [app name] and [device name] e.g. Firefox Preview on Pixel 3
Waiting on Strings confirmation.
Confirmed that it should be [app name] on [device name]
I think what you see in Invision is an artifact of Ryan customizing the name of his device, not pulling in metadata from somewhere else.
@liuche strings resolved
@vesta0 @mheubusch Close. It's best to take a look what Firefox does on other platforms to stay _in sync_. What it does is something like Vesta鈥檚 Firefox Preview on Pixel 3.

@ryanfeeley I'm seeing variance across the board, and was trying to match for Android. Firefox for Android and Firefox Beta for Android don't pull in a user's name either. Is this a Fenix issue or FxA issue? Also, are Firefox for Linux and Pocket and Lockwise displaying correctly too?

I don't have a linux device, but here is a screenshot of Lockwise, Pock and Send.

@mheubusch spoke with @ryanfeeley offline: [name]'s [app] on [device] is the way we have to have across all devices eventually so we should do the preferred way here (other platforms will update).
For any items that can appear multiple times, it would be great to have [name]'s [app] on [device] for all of them.
This is not fixed yet on the latest Nightly build 190731 (#12120612) with Google Pixel 3 (Android 9), Sony Xperia Z5 Premium (Android 7.1.1), and Windows 10.
This is how the device's names are displayed:

I mentioned this offline, but it seemed a conflict resolution when merging this PR seems to have broken it's functionality: https://github.com/mozilla-mobile/fenix/commit/8ff77b90f388187e04f6a376702c6a10873ea49e
Verified as fixed on RC 1.2.0-rc.1, and latest Nightly build 190801 with Motorola Moto G6 (Android 8), and Sony Xperia Z5 Premium (Android 7.1.1).
