Hi @dlsn – there isn’t a built-in way in the Site Editor to modify responsive breakpoints for blocks.
Could you provide the following to continue troubleshooting:
- a link to your site
- a screenshot showing what you’re not happy with on mobile. You can use a tool like https://snipboard.io/ and paste the generated link here, or use your preferred screenshot tool and upload the image to your Media Library. Then, insert an Image block here by clicking the + block inserter and selecting Image. Then, click “Insert from URL” and paste your Media Library URL into the block.
- browser name, version, and screen size used when taking the screenshot
Thanks!
