Support › MB Frontend Submission › Sorting on the Frontend isn't Working
Do you mean the sortable feature of the cloneable field? You can try to deactivate all plugins except Meta Box, MB extensions, switch to the standard theme of WordPress (Twenty TwentyTwo) and re-check this issue.
Yeah, those are the ones. I've tried all of that to no avail. What confuses me is that sortable text fields work fine, just not sortable groups.
