LED Color Bulbs Not Connected After Firmware Update

I have two Yeelight LED Color bulbs that had been working great with the Yeelight Android app. I got a notice that there was a firmware update so I installed it on both bulbs. Since then the bulbs are unrecognized by the app. I have tried resetting the bulbs and turning them off overnight. I can no longer control the bulbs through the app; they are stuck at 100% white. I am very frustrated.
