Hi, I'll start by saying how much I like ED Discovery and I really like the direction it's going in however I've been having problems with it updating, By this I mean that it used to only be a few seconds at the most behind what was happening in the game but as each app update came along the lag got worse. I had assumed this was an internet issue, that EDDis was waiting for some transfer to complete and this was reinforced by the fact that I had moved onto mobile broadband which is very laggy and the app lag got to the stage that it just would not update with what was happening in the game, you'd get the spinning blue arrow indicating tha it was busy, then it would stop and you'd have the normal mouse pointer but before you could do anything it would start spinning again. So I decided to unistall and revert to the 10.6 version which I did and noted that when I launched it it still had all my settings so clearly the uninstall does not remove all the data files, you should fix that. So I found all the other files and deleted them and then uninstalled and reinstalled 10.6 and great it's working again. Updated to 11.4.1 and it's still working, happy days. I then pinned my usual tabs and now it's not working again. After a bit of trial and error I've narrowed it down to the Missions tab as the culprit. If I remove it from the tab bar all is good. The only issue I have now is completing the full system data download but that, I think, is due to my less than optimal internet connection.
