I saw the prior threads regarding issues with Essential Grids having problems after the WP 5.5 update so I held off on making the update to my sites until WP 5.5 and Essential Grid 3.0.6 was reflected as being compatible on your documentation.
As I saw they are now listed as compatible I’ve gone ahead and applied both updates in a sandbox environment, but similar to what others reported earlier the grids have gone missing from my site.
For example, on the front page prior to applying the updates:

I’ve done some experimenting and found that if I create an entirely new section/row/column and insert the grids via shortcode leveraging the Raw element I can get them to show but I’m not able to get them to work in the previously built sections.
If you could investigate I’d greatly appreciate it. I’ll include the URL and login details in a secure note.
