Hi Michael, I am John J.D., a fellow Microsoft user like you.
I understand your frustration. You're not alone, many users are experiencing this. However, even though it might not reflect immediately, your searches could still be adding up behind the scenes. To make sure, try closing Edge or the Bing app and check the points again under "Search on Microsoft Bing." and check if it update the search points counter from there.
If issue persists please submit feedback directly to Bing Rewards team:

Thank you!
