WHITE is no longer a color option when creating or editing light Routines. It's been like this since a couple of updates ago. Luckily, I had an old device with v2.2.432925.0 on it, which works correctly, & Smart Switch came to the rescue. Note to all: You should turn OFF Automatic Updates in the Play Store, & make sure you have a copy of every app on another device before doing any updates. This will allow you to revert to a previous version when developers screw up an app with updates.
