Calendar invitations I receive no longer have Accept, Decline, Tentative buttons (since recent update)
Until the most recent Thunderbird update, if someone sent me a calendar invite from whatever electronic calendar solution they used, I would receive the invite by email and it would have buttons at the top to which I could respond: Accept, Decline, Tentative. If I accepted the invitation, the event was also automatically added to my own Calendar tab. Now when someone sends me a calendar invitation, I don't see any of the response buttons and therefore the event is also not saved to my Calendar. Instead, I need to manually enter it, which kind of defeats the purpose. How do I fix this?

Are you getting the invites on a mail address that has no calendar associated with it perhaps.
Each calendar has an email address associated. it is used to determine what calendar to accept invites to so it's absence could be why not buttons.
In a calendar tab, right click a calendar. in properties there will be an amail address for the calendar.
