New smart watch


I ave recently purched the smart watch M26 from and I'm having problems connecting it to my galaxy s8+. When i connect it via bluetooth it will not connect. Once i turn the Bluetooth on and pair them i get the pair number on both phone and watch match. Once i confirm they are the same i pair the 2 together. But unfortunately the phone tells me to make sure the device is on to pair. Anyone else had this problem and been able to make it work
