Hi ilumi nation!
This weekend there was a disruption that caused a group of users to not be able to login, but this has been resolved. If you are still having any issues logging into the app, please contact us at support@ilumi.co.
Apple has released their public update for iOS 10.1 and we have confirmed that both users with iPhone 7 and other devices updated to the new iOS 10 release are now able to connect to their devices. We highly recommend updating to the iOS 10.1 update in order to get connected to your lights again.
Let us know if you have any questions! We'd be happy to help.
Cheers,
team ilumi
