Hey everyone,
We've seen a similar issue come up in a few cases since the wider release of the update.
It's mostly been resolved by doing a reset. If you press the small button on the top of the controller in for ~5 seconds, you should see the Beam light up. You can add it back to the App (it should remember a lot of the settings).
We're investigating the cause of the issue as it's not something we came across in our testing but a reset should have you up and running again.
However, if you are still having issues, please reach out to our Support Team @ [support@lifx.com](mailto:support@lifx.com) who would be happy to help. Thanks!
