So last night my f5s automatically updated to firmware 3.30 (I thought I had all automatic updates off) and now the problems begin. The only reason I use A Garmin wearable is for the Erg IQ app and it was working fine until this (for me) useless update. Two of the three sessions from today are in the watch history and only one of the tree downloaded and is visible in Garmin Connect. This is a real disappointment as everything was working great and I track my heart rate info to manage my training efforts but if I can not rely on the f5s I do not know what to do. Is it possible to go back to the last firmware update or is it a done deal and I have to work with what appears to be unreliable 3.30.
