YouTube and AdSense earnings separate accounts
Starting Match 2022, Google will start to separate AdSense Accounts from YouTube accounts earnings.
This means that if you own an AdSense and YouTube account and you are earning through Google Ads, then the earnings will be managed from different accounts. Each account will have to reach the required payment threshold of $100.
It also means that you are required to have a payment method for each account. If you were using an AdSense account for payment then make sure that you have your YouTube payment account set.
Previous Youtube earnings data will remain in your AdSense account.
