I live in the US, and I haven’t experienced a lot of these as well. But I also don’t use a Microsoft Account and only use the MS store minimally for things the system requires to function decently. I am pretty sure it hits you with more ads if you’re logged in to your machine with a Microsoft Account instead of a Local Account. It’s part of why they’re pushing so hard for people to stop using local accounts. It’s easier to advertise to someone who can be strictly identified by their user account.
