Just since yesterday, for no reason I can think of, my provari's button isn't working right. I'm having to hold it down firmly enough to be uncomfortable to get it to light up and work, and sometimes there is a delay, sometimes it comes on intermittantly really fast which pops up the menu and starts scrolling madly through it. It has never had an issue before now, is their anything I can do short of mailing it to provape? I'd have to go buy another PV before I could do that.
