To watch a paid broadcast, you need to use LIVE Coins.
You can see how many LIVE Coins are required on the pop-up before a broadcast starts.
By tapping Watch you will be charged the listed amount of Coins and can immediately start watching the broadcast.
If you use LIVE Coins to watch a paid broadcast, you can watch it again during its viewing period by going to Viewing history at the bottom of the My Page screen or Paid broadcast history.
To see your paid broadcast history:
1. Tap My Page (the silhouette icon) at the bottom right of the screen.
2. Tap the Settings icon at the top right of the screen > Paid broadcast history.
If you use LIVE Coins to watch a paid broadcast, you can rewatch it anytime during the viewing period that's displayed when you make your payment. You can check how much time is left by going to Paid broadcast history.
For the steps to view your paid broadcast history, see this Help article.
