My YoCan Uni is blinking 3 times with one of my cartridges but I have tried the cartridge on another vape pen and it works, what do I do?

Answer:
The Yocan UNI flash 3 times means the vape cartridge connected incorrectly.

Please try to use a q-tip to clean the contact points of the adapter.

This just worked for me, thank you. Up to the clouds I go... Its so much happier up here, put the beer down and pick up some greenery!
