HI Johnny,
See my last 2 posts above about more tests of clean install of 26063.
A) In 1st case while still in default Dev channel, it can update the Xbox Identity Provider without the error message.
B) If I switch to Canary before Xbox Identity Provider has a chance to get updated to 12.110.15002.0, I get back the old problem. 😂😂🤷♂️
