Quoting because this is a new trick I’ve found that works. Leave the batteries out overnight and then email us if it doesn’t work.I also had issues and replacing the batteries did not work. Nate suggested I leave the batteries out for a while. I removed them overnight then reinstalled the same new batteries I pulled out and everything worked just fine. I'm sure it didn't need to set overnight, but at least a little while seemed to do the trick. maybe try that.
