Several occasions now. When using this app, I see that I have logged a punch, like when I am going out the door home for the day. Then the next day when I clock in, it will show me a missing punch from the previous punch out. Not sure whats going on, but it is slightly annoying to have to explain that the mobile app is not logging punches for me.. this has happened at least 12 times over the last 6 months. I think this needs to be checked into and an update sent out
