I have filed to flight plans with Skydemon theses days and it worked perfectly.
But I only get an email back from a Skydemon Server that the flight plan was submitted to officials.
I never get an answer that the flight plan is accepted correctly by DFS or someone else.
At my first attempt, I called DFS to make sure they have my flightplan - they had. For the second time (submitted in Switzerland) I took the risk, but anything was fine.
Filing a flight plan from the DFS-AIS Website, I can get an SMS as a receipt - good to know.
Can Skydemon do this also (or ask DFS to send it) ? My phone number is always in the submitted data.
Or can you link Skdemon to my DFS-account? I think other countries have similar Websites.
