What's the deal with GPS dropping after the new firmware and app updates?  I will not be flying until prop locks arrive but am concerned to say the least!

I do get daily solar activity reports and stumbled on this for today
CHANCE OF STORMS: NOAA forecasters estimate a 40% chance of polar geomagnetic storms on Jan. 15th when a CME is expected to sideswipe Earth's magnetic field. The storm cloud was propelled in our direction by a solar filament eruption three days ago. Residents of the Arctic, be alert for auroras. Aurora alerts

So could that have caused all of the GPS problems people are reporting after the firmware and app upgrades today?

inquiring minds.

I Just purchased a new P2V+ on Monday and haven't been able to get a GPS lock o it for longer than a few seconds.

For what its worth please take note:
Jan 15th was a good day for solar flare activity to interrupt GPS sat links.

Actually Jan 13th  there was a hefty solar flare warnings for GPS interruptions where on a few sites.
