Problem: I have multiple sandbox sites set up on discover-wp.com, and I would like to use import and export to combine the contents of these sites into one sandbox site.
Solution: The discover-wp.com sandbox sites have import capabilities disabled to prevent misuse of the system and for security reasons. It is not possible to import content into these sites directly, so it would be better to set up a separate sandbox on another server and import your exported sandbox content from discover-wp.com over in the new server.
Problem: I would like to display a grid of 'resources' that are in relationship with a topic on that topics page. Easy enough, but I would also like to display on that grid the Author of the resource. From my research, seems like I would need to create a nested view. I got it to work using the legacy 'views' but I'm not able to use any of the styling options available in the block editor (grid styles, border radius, etc.)
Solution: It may be necessary to use a nested view if the post relationship is many-to-many, or it may not be necessary if the post relationship is one-to-many. You may also be able to use the Block Editor to design the loop template of the nested View, separately from the editor of the parent View.
