Rachio Gen 2 keeps going offline lately

Hello, my device seems to have this problem now. I reboot the device and it’s online for some time and then goes offline after a run starts and the sprinklers stay on until I unplug the power to rachio. During manual runs, when I try stopping the run through the app, I get the spinning circle icon and nothing happens. It goes offline and the sprinkler stays on. The only way I can stop it is by discounting the power.
A little background: the device was plugged in yesterday after a while and the ownership was transfered back to me. Ever since, it seems to go offline after a run is started (manual and scheduled runs). The firmware version is 5-115. I checked for any available firmware updates through the app and there appears to be none. Please help!
