You can ignore it if you like. It works fine for me, and it will work as intended for you too if you figure out what's preventing it. Since it sounds like you're not talking about the dead of winter that points to your device not being able to get the weather data it needs in real time. I think you mentioned using an Apple Watch in another thread, and what I suggested earlier is a common issue among iOS users. I bet if you look into that you can get this sorted out with very little effort.
