An Elementor Pro site built back in October utilizing the Premium Addons plugin began having issues with the last 2 updates. When trying to edit a page/post, Elementor’s element/properties dashboard would gray out and display an endless spinning wheel. The only resolution found after testing each plugin was to rollback the Premium Addons for Elementor to version 4.9.45. Hopefully this will only have to be a temporary fix and the next update will address this issue.
