I got a message from my reward account that I get 5 points per search every 15 minutes.
In other words 15 points per 15 minutes. I hope this isn't what they plan to do because it will take the entire day to reach your maximum points per day.
I am having the same issue, only I get 20 points before it stops and I have to wait 12-15 minutes before it stars adding up again, and I repeats at the cap of 20 points before I have to wait again. I have sent 3 separate claims to MS, and the 3rd one was after they 1) responded after the 2nd claim and said "You earn points after 3 searches," and "try doing legitimate searches"; and 2) said 2nd claim was then closed by MS.
So, I sent the 3rd claim and said up front that if the issue is not resolved by the time I earn enough for a $50 MS gift card, then I would quit using Bing and Edge to go back to using Google for searches and any other Wb Browser for my usual internet stuff. I did it before when, back before they started using direct deposit with their digital gift cards, I was not receiving emails for gift card codes after redeeming my rewards points; and if I must do so again, then so be it.
REALLY sad how far MS has fallen from what it used to be.
