Removed Lightning and now get the message that it is not compatible when trying to reinstall
I was just starting to try and set up Lightning and Google calendar synchronization. I could not find the Lightning config options so I tried removing it with the intention of adding it again. No when I go to the add-ons manager I get this message: "This add-on is not compatible with your version of Thunderbird." for Lightning. So now I have no calendar at all!
Thunderbird version is 60.3.2.
