I've got 2.4 & 5G WiFi networks running constantly at home and this device would always connect on 2.4G instantly after saving activities. Suddenly it won't find these networks (even though they're running fine for all other devices in the house and I haven't changed any settings), so auto-upload, etc. won't work. Anyone else having this issue?
Gradient calculation & battery is also marginally worse since the last update for me too, so It's got me wondering whether it's the update at play...
