Please include a detailed description of your issue or question:
I flew from Canada to California Oct 25 and all that time in the top corner foreflight showed FltBox, No Towers. I since have flown multiple trips in the Palm Spings CA area and always show FltBox No Towers. I do seem to see traffic but not always in agreement with my ADS-B display on Aspen MFD. The FltBox is mounted in the glareshield of the window in a Bonanza with antenna’s pointing up. In the FlightBox utility it shows both channels selected. How can I determine if there is a problem or make sure it is receiving towers.

I have a similar issue. If I unplug the power and wait 10 seconds and plug it back in, I suddenly show connected to towers. However, it will cut out periodically as the flight continues. I believe I have the most current (2 years old) firmware update.
