Hello.
I changed plan back in September, but I still have the weather in my alarm screens, it just has not updated since September. How can I get rid of the weather info since it is old?
Taking a look at the account, those weather features have indeed been removed.
Try power cycling the panel to clear the issue. Unplug the transformer from the wall then unplug the internal battery. Leave the panel powered down for 30 seconds. Then plug in battery, then plug in the wall transformer. Once this process has completed and the panel rebooted, any change?
Should you need it, this video here will show you how to open the panel to unplug the battery.
