Hi,
I think it might be why people are seeing ads today in Premium.
I have seen a lot of reports today about Solitaire showing ads in Premium. It should typically resolve in a day or two without any action. I appreciate your patience while Microsoft works on the same. If it does not help, fill a support form:

I hope this information helps. If you have any more questions, don't hesitate to reach out.
