Same problem here. Send button is greyed out. True on both Mac and Windows.
The issue is definitely caused by Correct Identity; disabling the add-on solves the problem.
However, there's an easy fix: the previous version (1.4.3) still works fine. Just download it and reinstall it over 1.4.4.
It should therefore be pretty simple for the dev to find and resolve the problem. In the meantime, could version 1.4.4 be removed? It is annoying to be constantly asked if I want to upgrade to a version that I know is faulty. Thanks!
