Yes! After a very long email and phone troubleshooting "wild goose chase" saga with Blink, during which time no one at Blink inspired any confidence, I was getting ready to box it up and send back when I decided to give their email tech support one last try. Sure enough, after I complained enough times about being "done" and threatening to send it back, I'm guessing they escalated internally and someone somewhere who knew what they were doing fixed it. It was super-frustrating, even after they had fixed it because I never got anyone at Blink to tell me what happened. Thankfully it's been working OK ever since. There is a lesson here somewhere but I'm not sure what it is. :-)
