How do I get an update for Mp3tag for Mac?

How do I get an update for Mac version? I'm still using v1.2.2. Your 'Send Feedback' function doesn't work as it just opens Chrome and goes to Your email bounced as well. Things doesn't seem to be going very right here.

If you have bought the app via the Mac App Store, you can get the update via the Updates tab in the App Store app.

If you've bought a license code via the website, you can update via Mp3tag → Check for Updates....

The Send Feedback button uses the system-wide handler for mailto: URLs. Normally, this is but you might have reconfigured your system.
