I'm new to Metabox and I was wondering if the following was achievable - I want to add Gutenberg to a custom post made by another plugin.
The plugin is called ThirstyAffiliates (https://thirstyaffiliates.com/) which creates a custom post type "thirstylink", Was this possible through Metabox or was this something that needs to be coded in the plugin?
Enable the Block Editor (Gutenberg) for a custom post type made by another plugin is beyond the scope support of Meta Box. You can contact that plugin support to ask for help with this question.
