I created an activity in the mobile screen, and also scheduled a follow-up activity. Both activities show up in the List tab on the mobile screen.
However, when I look at the Activity List tab in the desktop screen, I only see the original activity and not the follow-up
However (again!), when I export data from the Activity table, both activities are in the first 2 rows of the CSV file.
Any idea why these wouldn't be showing up on the desktop list?
