Sorry if this has been asked before, but I don't have time to dig through a ton of posts at the moment. I just got my x cube ultra in the mail and want to set it up for Bluetooth. But the app keeps asking me for an ID and password. None of the cards that came with the mod have a password. The security code on the side of the box isn't working, and the website for Smok won't work to let me authenticate it. Has anyone else had is issue? Any ideas?
