This is NOT a 'I need help' thread!
Greetings Xbox Support -- Please close this thread once you have read this and passed it along towards the development team.
There is a current bug I have discovered on the Xbox.com website.
If you change your gamer-picture via Xbox.com it only uses the thumbnail image and not the full resolution image of the gamer-pic as it does when you change it via the Xbox One console.
Let me show you an example.
This is how your gamer-picture appears on your profile if you change it from the Xbox One console.
This is how your gamer-picture appears if you change it using Xbox.com
I understand this is a very minor bug, but I figured it was best to go ahead and post it here, hoping an Official Xbox Support employee could pass it along to a developer who could remedy this.
