Thanks for filing this issue! I see it's identical to bug 1860785. Thus, I'd say it's not related to this migration. However, there's definitely a pattern. Lorand, could you try to narrow down what could be the root cause?

As much as we could find out (with the help of my colleague) was that the request sent to this URL gets an error that leaves the default wallpaper only, but what can be the issue here is that the request is sent only while starting the application, and not when the application is resumed as well.

Looking at https://github.com/mozilla-mobile/firefox-android/blob/8caf736b5cb649db688dbcbc2e6cefec90ceccb4/taskcluster/android_taskgraph/transforms/build_android_app.py#L118, we seem to only set the wallpaper url if running on level 3, so e.g. not for PRs currently. That also explains why the wallpapers are missing on oak, which is level 1.
This seems to date back to the feature addition in https://github.com/mozilla-mobile/fenix/commit/9dc0506ec200ab679aaa32064862b48b5ec65997.

Aha! That makes total sense, then! So this is by-design. I'll close this issue as WONTFIX but feel free to reopen it if wallpapers are still missing on Nightly after March 18th.

Thanks :jcristau for digging up this explanation!
