I’ve confirmed that window.Twitch.ext.features.isBitsEnabled always returns “undefined” in the developer rig. This makes testing a UX that respects the isBitsEnabled flag a bit problematic.

Bits are generally not supported well in the Developer Rig, according to conversations on discord ([https://discord.gg/cEDe95](https://discord.gg/cEDe95)). Unfortunately, discord conversations don’t show up in Google search and I wasted a lot of time trying to debug this. Hopefully this forum topic will show up in such a search and save some other developer from wasting time.

window.Twitch.ext.features.isBitsEnabled is undefined in the Twitch Developer Rig.
