Norton could be causing this behavior. It may also be your Focus Assist settings you have Windows configured to. See here for more information:
Given the many reports received of Ad notifications not appearing for some users, we’ve compiled a short list of [Windows] settings to check to ensure that the Ads platform and your OS play nicely together.
