RSS Import not updating automatically

I setup the calendar by adding a calendar, from URL (used the following link webcal://trinityschooloftexas.myschoolapp.com/podium/feed/iCal.aspx?z=5P15AdKl0kjhSCOPIRxZBCPA5cM3H3J1WszADX4fyhFMehEV%2fZWf2BL%2f6qG7lWrXZB4O4yVw%2fjTmy6XqR37K%2fg%3d%3d) and it imports over correctly, however when we add or make changes to events they do not update through jevents.

Please advise.
