I have a series of groups within tabs that are saving to custom DB tables. I am specifically using groups because I need to clone the fields a few times within each tab.
I cannot get the 'std' setting to work for hidden fields and I cannot get the save_format setting to work for dateTime fields or date fields.
Additionally, I cannot get the delete button to work for a file field. Reference this ticket: https://support.metabox.io/topic/file-field-not-force-deleting/
All plugins are up to date as of 2019/11/14.
