Here is a question from a Yocan UNI Pro user:
My button has stopped working and can no longer use
Which button, power button or the up/down button?
Please check is there any concentrate residue surround it. If so, please use a q-tip with iso to clean it.
If the button broke, and can't clickable, please contact Yocan support team.
