Blank profile picture on Microsoft store

Same here. Everywhere is ok except MS store for both laptop.

I have the same problem here after changing the profile picture on my Microsoft account.
The picture changed correctly on the account itself, and on the Windows login screen, but the Windows Photos app still showed the old picture even after waiting a while, and the other Microsoft apps just showed a blank icon.
I deleted the old picture's file in the Photos app data folder, and there is now no picture at all on the Photos app either, or still any of the other Store apps. They all show logged in correctly, with the correct picture on the login dialogue window if I click on the icon, but there is just a generic icon where the picture should be on all the apps themselves, including the Microsoft Store app.
