anyone seeing their MS account thumbnail pic not displaying tonight ?

In store app our family user accounts usually have the associated pic of that person in the top right. Noticed tonight on all our machines the pic is now just generic grey. It's not loading the thumbnail. It's a bit of a mix really. some user accounts it's still there, for others it is not. And it's not consistent across PCs, on one mine is generic grey, but on the other pc my pic displays. Guess because it's cached or something. All accounts are logged in. I notice the generic pic is there in some other apps like weather too and even the default MS homepage in edge. Anyone else see the same? I’m guessing something on MS end is not talking at the moment. It's a minor thing but just looks a bit lame and doesn't help my OCD tendencies! Never a quiet time with Windows 10, always something is malfunctioning!
