The attendees I select are not receiving their invites to my calendar events. My version of Thunderbird (TB) is 115.9.0 (64-bit). I check my sent folder and it does not send. Older versions of TB, the Calendar invite worked and I can see it was sent from the sent folder. Please note that I am not tech savvy and I need a solution that an average person can employ. If someone has a solution, please get it in step by step instructions and assume I know next to nothing.
