No even when it updates it doesn't match the app. I have it set for the most frequent update which is an hour Btw. It's a bad weather app. And htc chose to force users to be stuck with it.You didn't say the widget never matches the app..... Anyway, this is probably because you have the widget to update infrequently, but as soon as you open the app IT updates immediately and gets the most current temp. If the widget update frequency is set to 1 hour, the temp showing on the widget could be as much as 59 minutes old. You can, I suspect, set the widget to update more frequently, at the expense of battery life. That's not a bug. Having the widget update in real time would kill your battery, and then you'd complain about that.
