Hi there,
Thanks for reaching out! If you’d like to modify the output of your iCal feeds to remove the description field, you can achieve this with custom code using the tribe_ical_feed_item filter. For more context on how to use this filter in your theme’s functions.php file, you can refer to the original source file for iCal exports, which is located in the plugin folder for The Events Calendar at /the-events-calendar/src/Tribe/iCal.php. Please note that we aren’t able to provide code examples for this type of customization, nor can we guarantee that ICS files modified in this way will be compatible with ICS-supporting applications.
I hope that helps to get you started here! 🙂 Thanks again, and let us know if you should have any other questions!
