Issue with adding Hue Go to Apple Watch app via bluetooth

Hi, I have 2 Hue Go lamps, but when I try to add them in Essentials Apple Watch app via bluetooth (not bridge), app discovers only one of them. It just doesn’t see another one, though iOS app adds both of them without any issues. Also after adding the 1st one, while still trying to add the 2nd one, app crashes when I choose Light from device adding menu. Any ideas what might be going wrong here? It’s absolutely amazing to have ability to control Hue Go in bluetooth mode from watch. Thx in advance!
