Hello, since last updatze, the filter rwmb_frontend_field_value_post_id is not working.
I've doubled checked everything on my end and the $value returned is ok, but the form is not populating the post data.
Thanks.
There is an issue with the filter hook rwmb_frontend_field_value_post_id in the latest version of MB Frontend Submission. I've escalated this issue to the development team to fix it for the next update of MB plugins.
