I bought the yocan evolve plus in late January & I cleaned the vape w isopropyl now when i turn it on it keeps flashing 3 times & nothing is working
The Yocan Evolve Plus flash 3 times means the battery wont detect the coil, please check the connections.
Do you have a brand new coil?
If so, please install this new one.
