Where did you get information that the current version is 4.23.2? It’s a number of current free version at wordpress.org plugins repository? Free and Pro version numbers don’t match sometime. I added a ‘core version’ information into the Pro version changes list for this reason.

According to the Download page (you should login 1st) the current Pro version is 4.21.1. I just plan to publish Pro version 4.23 (with core (free) version 4.23.2 included) after fixing some minor issues recently discovered during tests.

If you don’t wish to experiment with manual version change at the user-role-editor-pro.php file, please wait a little until I publish Pro version 4.23 and let’s return to the subject then.
