Same issue.
I try to use https://icalendar.org/ to validate the .ICS file produce for this plug-in. Error found was this:
- Property parameter values must not contain the DQUOTE (“) character.?near line # 6 Reference:?3.2. Property Parameters
For reference, these first line of the ICS file generate by Events Manager
(for they seems fine)
