Welcome! This forum has a treasure trove of great info – Scouters helping Scouters! Just a heads up, though - all content, information, and opinions shared on this forum are those of the author, not the BSA.
Are there different versions of ICS that may effect what can be done? Is the URL information transmitted in some type of envelope where display is controlled by the end user’s calendar display features (or options) or is the ICS server embedding the link information in the text of the event description when transmitted via ICS? I suspect we need to know which version of ICS is being used to transmit the calendar event information.
The text is in the actual ICS file which resides at scoutbook.com.
I opened the ICS file with a text editor and this is one of the many lines where the text is added. No matter what way I import the information, it will appear on every entry.
