Long load time for updating profile picture

Investigate this, I find this behavior very odd... kinda skeptical as to if this is a frontend problem or what is really going on.

Start by reviewing the linked Slack discussion and reproducing the profile-picture update flow. No source files, tests, or entry points are named, so locate the relevant React Native code before investigating whether the delay is in the frontend or elsewhere. Done means the source of the long load time is identified and the profile-picture update behavior is verified.
