@SusanWojcicki hello can you please take a look at the YouTube superchat you guys really take a huge percentage from the creators who work hard to produce great content thank you.
Rev share is calculated post Apple service fee and there may be other charges like sales tax. This is why actual Super Chat revenue may vary as noted here: https://yt.be/help/Azns . Also, keep in mind that sales tax varies per region and it's based on where the viewer is located.
