@kevinwhoffman @DevinWalker I worked on this issue and now blocks are working with WP 5.0.0 Beta but I am facing one issue. Gutenberg API somewhere caches API results before render and it will not rerender block if past query repeat. I check for a solution but did not find.

I know somewhere maybe we need to bypass this function or manually call cache deletion function: https://github.com/WordPress/gutenberg/blob/aec940810eaa73e9fe54c2a0e3dd591634158aa5/packages/data/src/resolvers-cache-middleware.js#L25

I will reach out to gutenberg pro developers and let know about it.

@kevinwhoffman or @DevinWalker can you take care of styling issues: #3827 (comment)

[kevinwhoffman]

I'll create a new issue to resolve block styling issues. Leave this open for now.

[kevinwhoffman]

Closing. Remaining block issues for WP 5.0 will be resolved in #3887.
