I did a manual software update on my Venu 2 Plus. I've discovered that if the battery drain seems excessive for a day or 2, it needs to do a software update. Afterwards, it sits on this screen. I can hit a button and back out if it, but I'm left wondering if it installed the update? I rebooted the watch, and selected to search for a software update, and it appears to download the same update again. Why does it not say "update successful" instead, our something to indicate it's done? How do you complete the update?
