Profile pic only syncs from desktop to mobile, but not from mobile to desktop

[ConfidentKeyboard]

Describe the bug
Me and another user both set our profile pics on mobile (android), but when I visit my instance in the browser (Firefox) on my desktop, both our profile pics are blank. So I tried adding a profile pic in the browser on my desktop, assuming it would also not sync. But it overwrote my profile pic on the mobile app. Of course this is a minor issue, purely aesthetics - but wanted to point it out.

To Reproduce
Steps to reproduce the behavior:

1. Start with no profile pic.
2. Add a profile pic on mobile app.
3. Check desktop browser for profile pic to sync.

Expected behavior
Profile pic added via any device/browser/app should sync across all others.
