My service provider attempted to trouble shoot it, so did GoDaddy.
It seems to have been on the Wordpress.org side. It was really strange. I could edit one site using Pro totally fine. Yet the other site was completely failing at the Wordpress dashboard level to load Pro editing, & suspiciously unable to upload any new media as well (found this out when I tried to at least get the images uploaded). Everything else on the WP dashboard seemingly worked perfectly fine. Yet no topics suggested testing this when we are facing a failing to load Pro editing.
So if you are having issues with an endless spinning wheel, I would STRONGLY suggest, attempting to upload media from the WP side instead of the Pro interface. If you are like me, that won’t work & you may have to wait for WP to solve whatever problems they are having.
Without testing the media uploading, I would of continued to think it was a a Pro issue, because no other topic suggested testing the for media uploading ability. Everything else in the main dashboard worked as normal.
