Hello,
I use Safari on MacOs. Since a couple of days the main menu on the left in connect disappears, even when I click the menu open button 
I can open it, but when I chose an option the menu collapse again, it used to stay open. Also, since the same time the Lactate Threshold screen shows only the current data. The graph on 4w and 12w are blank.





. For menu that is hide by default is simple ... body tag class minimize-main-nav have to be removed and menu stay open .. if is close by icon if you go over menu is open by main-nav-hover and return to close if you go out of menu . but if you return to open with icon stay always open .. i don't know with is so difficult to solve this problem ... With this two stupid fix return to works with firefox and windows 7 and the other problem for who whant the menu always open ..
