cannot recommend mcc anymore. Some months ago, all over sudden some of my flights were only partially synced to my mobile devices. And database (pilots) as well. I am emailing to them since months, sent screenshots, they reply with huge (weeks!) delay, problem is not solved. Once they replied I need to delete and re-install the app. Thank you, I did, since then everything is gone (on my mobile). I am really p****d, will watch this space and probably change soon.
