Here is her/his question:
I bought my Yocan Evolve Plus XL vape about 3-4 weeks ago and it already stopped working.
Try to charge your device. When you plug the cable, the light will on. And once it fully charged, the indicator light will turn off.
Install a brand new coil or Yocan Evolve Plus XL atomizer.
If the light always off, no matter how many time your tap. Your battery is die, you need to get a replacement battery.
If flashing 3 times, check the connection, and clean the contact point.
If still can't work, please contact the shop you bought it from.
