Drupal 8.x

Is there anyway to see a content types display modes through jsonapi? This would allow be to configure teaser etc. for display on decoupled Drupal. 

Views UI: Administer views

I need to add anonymous access for this so that views show up on the JSON:API. 

Is this the best method to see my views on /jsonapi?

What are the security concerns that the message is hinting at?

I have set the responsive priority the way I need it and those columns hide perfectly in the views preview, but not on the actual site EXAMPLE HERE

Is there a known issue with responsive priority in the tables format, or am I just missing something really basic?

I'm using Drupal 8.8.1 with Bootstrap 3.21 theme.

I have installed Drupal 8.8.1 successfully, but get an error when I try to use Configuration Sync. I'm a Drupal newbie and cannot understand how to solve this error:

CONFIGURATION SYNC DIRECTORY Not present Your sites/drupal-8-8-1cj.dd/settings.php file must define the $settings['config_sync_directory'] setting as a string containing the directory in which configuration files can be found.

I also have a second error, I do not know if they are related (it doesn't sound to me like they would be):

We use Connect OpenID and Microsoft for Single Sign on. My problem occurs when a user clicks on a hyperlink in Microsoft Word. The user will sign on but the page returns access denied. The users permissions should allow them to access the page. They are able to access when the url is pasted into the browser. The problem is similar to the one described in this link: https://docs.microsoft.com/en-us/office/troubleshoot/office/click-hyperlink-to-sso-website.
