Sorry, Fossil, please try again. A few weeks ago, syncing via the app slowed to snail's pace, often hanging during the process. Recent update seemed to improve a bit but the alert toggles are now unresponsive, either leading to a timeout or just not registering at all. Such a shame - I love my HR hybrid watch, but if the app continues without improvement, it's going to become unusable after 8 months, which wouldn't be good value for money, nor environmental sustainability.
