Effect creator crashes when tapping save on iOS

Thanks for sending me the screen recording. I was able to reproduce the crash. The crash will be fixed in the next update (1.16.3 on iOS). It should be available within a few days.

There is a workaround available: before you tap the Save button, first disable the switch for Show advanced settings. Then after that tap the Save button. The app should not crash in this case and the effect will still be saved the same.

For turning lights on in a sequence, you would also need to enable the setting Toggle light states in frames. What this setting does is make sure that the scenes can turn the lights on.
