I am trying to: create custom post types with custom fields
when using options, the checkbox for custom fields will not save as checked
I had upgraded to WP 5.3
downgrading to 5.2 solved the issue
Hi, I'm able to see the same symptoms so I've escalated this to my 2nd tier support team. One thing to note is that if you go to Toolset > Post Types and edit this post type, there are options for "Sections to display when editing...". If I check the Custom Field checkbox here, I can then use the Block Editor option more effectively. This is a bit confusing so I've asked for some clarification here. I'll let you know what I find out.
We have escalated this as a usability issue to the developers, and are waiting to hear back. My 2nd tier support team feels that managing Custom Fields from the block menu shouldn't be possible if the custom post type has the Custom Fields section turned off in the post type editor. I'll let you know as I receive more information about that from the developers.
Okay our developers have investigated further and determined that this is a bug in the Block Editor of WordPress. Types is registering the Custom Fields panel correctly based on the settings in the post type editor, but the Block Editor does not respect the setting and always offers the Custom Fields panel option, even if the panel is disabled in the post type editor. This is a bug in the Block Editor, and there's nothing we can do in our software to change this behavior.
