My F1 had dropped off the Wi-Fi for the umpteenth time so I gave it a reboot and checked the settings to see if it connected okay. While in the Settings pages I check for upgrades, as this is something I do often on any devices I own that are full of bugs!
Low and behold, V2.5.2 is available and now installed. Let's hope some good fixes have been implemented.
It still has terrible connection issues with the Android app, which is still on version V1.7.0
