Update ACPT Post Meta with Pro Forms

Based on a recent community question, I have been trying to update ACPT custom fields using Pro Forms, and so far, I cannot seem to get it to work.

Anyone have any tips or suggestions?

Hmm… last time I tried it it worked so far. Is the meta just not being updated? Or are you getting an error?

There are no errors, the default post fields are being updated successfully but the post meta is not being updated.

I can send login details to the InstaWP website if needed.
