Hi, try changing the feed ordering (tab You > > Feed Ordering > switch to Latest Activities), that might help...

Tried it both ways. However good news is that I found my missing rides. Even when feed ordering is “latest”, the activities are jumbled, not in date order). my new rides are several pages down ( I have a lot of friends)

even when I post a new ride, it gets inserted several pages down  this behaviour is new  it just started a couple of weeks ago, and it doesn’t happen every time  

Hmm, that sounds like a bug then

About a month ago Strava made a change to feed ordering. When you change the setting it only applies to new activities and won’t change the display for anything older (so those will still be in the “personalized” order rather than latest).

See Scout’s reply which gives a bit of detail on how the feed is ordered
