Since one week I have the FR245. The last few days I used the alarm clock in the morning. I like to stay in bed a bit longer so I press snooze. After the first snooze there is no BT symbol anymore. Also when I switch off the alarm after the first or second snooze. Sometimes the connection comes back, sometimes not. The connection is lost during the day anyway (phone with Android 8). I have to clean app cache, stop the app and wait until restart or I open the app and Connect IQ and after a few minutes connection is back). Firmware of the watch is 11.10. My FR735 also lost connection during the day but not during alarm clock snooze.
