It does not seem like trying to sort the Activities table on “Duration” or the lock symbol will end up showing the workouts in sort order (in either direction). It’s been like this for quite some time, are you working on a fix?
Hello Mathias. We’re not seeing any sorting issues with Duration. If you are, please send support@xertonline.com a description of what you’re seeing. We will be looking at the fixing the issue with sorting by lock once we resolve other issues that have higher importance. It is on our list of to-dos.
