Issue with updating profile picture

Hi everyone,
My profile picture recently vanished on its own.
I uploaded a new, completely standard photo of my face taken at the beach (just head and shoulders).
Right after, it was cleared again, and the app temporarily disabled my ability to update my details until tomorrow at 12:00 PM.

Could the automated system be misinterpreting visible shoulders/skin as unsuitable content? Has anyone seen this happen before, and what is the best way to set a photo again safely once the timer ends?

Thanks!
