Weird.
I got an email a day or so ago that said there was a Battery 4 update. So I open NA today. It (NA) updates. No update for Battery 4 shows up.
This has happened to me before. When it did, the update showed up about two weeks later (after opening NA every day waiting to see the update).
I'm thinking their product and NA updates get their nickers in a twist somehow. I'll say they have two different teams (as they should) who don't talk to each other (even though they should).
