I'm using IronSource for mediating rewards video. The first time it works OK but there's no way of loading the reward video second time without killing the app.
I checked their SDK and there's no loadReward or requestReward in their API. The first video loads automatically when IronSource.init(context, mAppKey, IronSource.AD_UNIT.REWARDED_VIDEO) is called.
How can I load the second reward video?
