Ok, Gert I will do my best to solve this issue. It's good that you're explaining the problem in more details. I copy and paste your messages to the Tech team.
As I said before, they tested it and things worked fine for them.
But, let me ask you, is it something that has been happening just now or this was always a problem on TrekEarth?
Is it every day that your recent activity goes to zero around 1AM PST?
Who else is experiencing this problem?
All this information will help us understand what is happening exactly with the recent activity.
