Can't remember which version change it was where iZotope removed the reverb module in a newer version of Ozone (I think it may have been going from V5 to V6).

Cheers for the reply..yeah I don't want or need Ozone 9, but it seems Ozone 8 isn't stable with Ultimate 2020.9.

Projects with Ozone 8 are at least recalling, but make Pro Tools unstable, so are not a long term solution.

..& this is the problem...I should imagine in a couple of OS updates time Ozone 8 will not load at all.

Compare this to (for instance) a stock AVID plugin, or even something like Sonnox inflator, or any of the excellent Stephen Massey range, where I can recall on old PT8 session & all the settings will load up just fine.
