2.0 has blocker-level bugs; company is unresponsive

Although version 1.x of the All in One Event Calendar worked adequately, since the 2.0 upgrade last month, everything has been a disaster. Our site’s calendar is no longer functional, with duplicated events and many UI bugs. Additionally, the only way to bring up issues now is with a forum that rarely gets input from employees. My impression is that the development team is way over their heads, and that the company is unable to manage software quality and delivery anymore.

Avoid this plugin like the plague.
