I was super happy with the 'send later' functionality. After I updated Thunderbird, it did not work anymore. Very disappointed that I was not warned about this before the update. I should have, sure thing, delayed the update. Now I lost a very important feature...

In general, let there no misunderstanding, I AM MORE THAN HAPPY WITH THUNDERBIRD IN GENERAL.

There is a beta version of Send Later for Thunderbird 78+, which will be released here within the week. In the mean time you can install it using the .xpi package from here: https://github.com/Extended-Thunder/send-later/releases

Also note, there is literally no way for Send Later to know that you are thinking about updating Thunderbird, so it can't warn you before you do that.
