Basically, for some time now my custom Gamerpic has stopped showing and now a predefined grey face is shown, when I search on xbox not even that face appears in the official Minecraft Gamerpics, I changed my Gamerpic over and over again, checked if it was a conflict with the Xbox security privacy options and still it doesn't do anything and remains the same, My friends have their Gamerpic and I just have a gray photo
This is working as intended per the changelog:

Note that only Marketplace skins and Character Creator skins are supported at this time, so if you have a custom skin equipped, one of the default skins or your previously equipped Marketplace/Character Creator skin will be shown instead. This issue is being tracked at MCPE-189765.
