Took 2 hours to connect 1x 6ft rgbww wifi strip with the app on a galaxy note 9 & galaxy s10. Wifi is 2.4Ghz & 5/5 strenght. The app/ strip either don't like samsung devices or my Netgear router... The strip would be in pairing mode & stop at the same time the app was detecting it, halting the pairing. Every time! I had a 2nd one to test and we actually bought quite a bit more, but the same thing happened with this one. To the point the succesfull pairing almost felt like luck. App needs work.
