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 doesn't get written to a file. SkyDemon tries to parse the data returned, and if there's an exception while parsing it, that's what triggers the error being discussed.
