issue resolved by MANUALLY installing plugins (download from ADD-ONS on MainWP corporate site account profile) .
as well as updating LICENSE API - evidently it changed.. Not sure when or why but…
however even after updating LICENSE API KEY —> purging all cache —> still had issues installing the ADD-ons via WP dashboard plugin updates. Had to do it manually
The steps outlined in that document usually help resolve such issues.
But if you’re still having problems installing or updating our add-ons even after performing those steps, please open a private help desk ticket so we can examine your setup.
