1. Is the content template meant to be a part of my post, or the entire thing? (meaning just some fields that I place on the post template in the full site editor, or something else?
2. For the life of me, I can't seem to place repeating fields, and it is driving me crazy. I have a repeating field on my post type that represents a row of images, and another repeating field in each for the images in that row (see attached image). I am unable to add the repeating images inside the repeating row in a content template, can you help please?
This is SO frustrating! NO matter what I do (creating relationships or repeating fields), I keep getting this type of warning about nested views not being supported at the moment. I am so regretting "upgrading" to the latest version, nothing works anymore and I am about to throw the whole thing out the window. Why is this so impossible? I just want to show rows of images on a custom page! I used to be able to do this with views templates, but nothing is the same anymore and it seems like you removed a ton of functionality from the product.
I found that I was able to disable toolset blocks and re-enable toolset views which actually works. Unless I am missing something, toolset blocks is in no way ready for prime time, I wasted hours trying to do something that took me a few minutes with views.
I see you have repating field group and you want to display but where and how exactly you want to display it. If you have a block view set to display post type and with that post type you have repeating field group then you should create a view in legacy mode that should be set to query the repeating field group and add this legacy view using "Fields and Text" or shortcode block inside your view block loop. That way while using block view you can add nested view.
