According to Instagram, "Reels Play bonuses are opportunities for creators to earn money directly from Facebook and Instagram for creating content that their communities love."
It's simple: content creators may earn money according to the number of times their Reel is seen. All you have to do is share Reels to Facebook and Instagram if you have a company or creator account (and access to the program). Instagram will reward Reels that receive at least 1 million views in a 30-day period.
NOTE: The Reels Play bonus program is now offered to a limited number of authors in the United States.
