When I first started using the app, I was generally satisfied. However, in the past 2 days an update has broken the app for myself and my partner. Neither of us can log into the app any longer (despite being able to log into their website with the same information), which has made my fitbit Versa basically useless for all the reasons I bought it. On top of that, I submitted a complaint before writing this review, and they basically sent an automated email directing me to some forums and FAQ page saying they don't offer support via email anymore. This is pretty terrible customer service, especially consider the app is 100% necessary for getting the full value of any of their wearable products.
