When Waves updated the Shell from 9.0 to 9.2, and I added the API bundle, Sonar held the version 9.0 hostage to all my sessions, since it was looking for VERY specific plug-in versions (sees 9.0 and 9.2 WaveShell as different plug-ins), so the complete disaster that was the upgrade sought some extra procedures from Waves to clean up - Followed by many, many hours of manual Sonar session recovery has be suspect that there's still something wrong with either one. All of this because Sonar didn't see the higher version of Waves plug-ins as the same plug-ins.
Maybe it's how they treat competition...
