Here is a Yocan fan question.
My unit won't charge. I've only had it for about a month. I have the UNI Pro.
Please check if there is any information on the display when you charge it.
The battery icon on the screen should grow.
As for the no atomizer issues, please refer to below.
Take your Yocan Uni Pro magnetic adapter and start screwing it on your cart until you feel even a little bit of resistance. Once you do, screw just a little bit more to make sure the adapter isn't loose, and put it in the Uni Pro and try and see if it works. Make sure to not screw your carts all the way in. You should only be screwing enough to secure the adapter.
