I have this problem every time I go flying with SkyDemon:

When I am on the ground with Wifi connected, SkyDemon (version 3.4.4.23 for iPad) downloads and interprets all data successfully and doesn't have any errors.
When I am in the airplane with 3G/4G connection on iPad Air, SkyDemon gives me these error messages:

Corrupt data detected while interpreting downloaded GAFOR information.
Corrupt data detected while interpreting downloaded SIGMET information.
Corrupt data detected while interpreting downloaded TAF/METAR information.



They pop out all the time until I lose the connection which is pretty distracting. What causes these errors and how to get fi them?

It's not a connectivity problem. It's the data being tampered with enroute. This is unusual and should not be happening, so we're definitely happier with the standard error messages than we would be either ignoring it, or showing a new kind of error interface which we'd have to invent.

Next time you see it, quickly switch to your web browser and try going to our website, and see what happens.

Hi Tim,
is there any way to see what the corrupt data is?
I've just got a 'Corrupt data detected while interpreting downloaded Forecast Wind information' - and a web browser opens up just fine - and no mention of corrupt METARs/TAFs/etc. 
I wasn't sure if the 'corrupt data' gets written to a temporary file somewhere?
I realise this may be a different corruption cause than the mobile network meddling.
