Hi, there
I found this thread as I am having similar issues.
I'm trying to show my custom post type in my newsletter using the Blog Posts block.
When I edit the block I see "Last posts. Custom post types can be added using our Advanced Composer Blocks Addon." but see no options to select my CPT.
I do have the Extended Composer Blocks addon installed and active, but the older v1.1.9, as my Premium licence expired in November.
To clear up any doubt, should I be able to select my CPT in the compositor?
I see from the documentation theme PHP needs to be modifide to use CPTs.
Are the options missing because my addons are out of date or out of sync with the core plugin?
If my addons are out of date and I need to extend Premium, that's fine, I just want to be clear that is going to solve my issue.
