Hi again, would you be interested in signing up for the beta updates? A new update 1.22.0 (6) is available in Apple TestFlight which may or may not fix this issue. See for details: Join the beta - Try new features before they are officially released
Note that beta version could be more unstable that App Store versions, so please keep that in mind. If you do not want to join, please wait for the update on the App Store. You can always switch back from TestFlight to App Store by uninstalling the Hue Essentials TestFlight version, and reinstalling it from the App Store.
Let me know if you have any questions.
