OK Mark, some good news, I have a solution.
I haven't tried it on your site because I'm not sure what you already implemented, I understand you've been registering conditional shortcodes for conditional checks etc.
I started from scratch on my own test site and have a working solution, so let me share that with you.
First, I can confirm/clarify that you must add translations of posts to the Post Group if you want the translations to be visible to the restricted users, it doesn't happen automatically. (I can imagine there may be use cases where you wouldn't want that to happen, but if you have a strong opinion about it let me know and I can share with the devs.)
So assuming you have set up the Post Group accordingly, you'll want to register the following custom shortcode:
/**
* Check permission to read post
*/
add_shortcode('allowed', function () {
$userid = get_current_user_id();
global $post;
$allowed = apply_filters( 'toolset_access_api_get_post_permissions', true, $post, 'read', $userid, ICL_LANGUAGE_CODE );
$return = ( $allowed ) ? 1:0;
return $return;
});
It uses the public Access API filter toolset_access_api_get_post_permissions which can be used to check whether the current user has permission to read a post or not (https://toolset.com/documentation/programmer-reference/access-api-filters/#toolset_access_api_get_post_permissions).
It will return 1 if true, 0 otherwise.
After registering the custom shortcode at Toolset > Settings > Front-end Content you can use it inside a conditional shortcode in the output of your View, like so:
<wpv-loop>
[wpv-conditional if="( '[allowed]' eq '1' )"]<h3>[wpv-post-link]</h3>[/wpv-conditional]
</wpv-loop>
That View is inserted on some page (and the page is translated, and contains the same View).
Without my custom shortcode, if a user that has no rights to see the post type visits the View on the front end they will see all the posts (because Access doesn't affect the output of the View, even when the posts are added to a Post Group to make them visible to this user with the restricted role).
But with the custom shortcode the restricted user now only sees the posts belonging to the Post Group. If they switch to another language they will also only see posts belonging to the Post Group (remembering that the translations need to be added to the group).
Can you try the same on your own site?
