The profile photo keeps disappearing

Hey, it happened before this week, and I thought I did some wrong click somewhere, so I re-added my profile photo, but just right now it happened again: I went to the fitness blender page, on my phone, the dashboard was still showing in the window from hours ago, but when it refreshed, I could literally watch the photo disappear again. Just wanted to let you know, maybe you can fix that. Anybody else having that issue?
