A program that grants points for using Bing search, which users can redeem for gift cards, sweepstakes entries, or charitable donations.
I've been finding that the daily quiz in the Bing app doesn't bring up the quiz, it just links to the background information. This happens on my Android tablet.
I have found that if I launch the Edge browser and access Microsoft Rewards, I can do the quiz successfully.
I also, a few days ago, waited until the following morning and used the Bing app on my Android phone and that also allowed the quiz to work.
I've just cleared the cache on the Bing app on tablet so will see whether that had any effect tomorrow.
I use Brave as my default browser. I don't know whether that has any effect. It can cause some pages to fail.
