There is currently a bug where the Grid does not display and attaches an image to the elements only in the back-end. Front-end works fine which is the most important part. With that said, there is no incompatibility. Sorry if you got confused with my previous reply.
I understand your frustration but we could not remove The Grid in our extensions list because of a bug. Our development team is systematically working to resolve all bugs but please note that not all of them are easy to solve. Your patience on this matter would be very much appreciated.
What I suggested is only temporary. Alternatively, you could work on Skeleton mode so you could see The Grid element (also temporary).
We’re very sorry for this inconvenience.
