Mine works, It just takes way too long for it to load. I find that if I pull the map up and zoom out as far as possible, allow for it to fully load the information (5 min +) and it shows the fronts H/L's then zoom back into local. It does work for me, I just have to be patient. When I'm going to be paying attention closely to the weather, like on my way to launch my boat to fish that day, I'll pull it up about 30 minutes out from the marina and let it do its' thing and be able to check the radar. First world problem, but it should be much faster than it is.
I usually opt for my Wunderground app. on my phone and check things that way. Radar loads on it PDQ, plus it has an hourly forecast with wind speed, direction, barometric pressure (important for fishing), and I can search it to check all that anywhere in the country I'll be heading to.
