Hi there, @1callservice,
I trust, as you mentioned, that your certificate settings are all good as per this certificate visibility documentation page and certificate settings page.
I also trust your settings would look like the ones in the screenshot below:

If all looks good, can you tell me more about that? Did the system return any errors or messages when you tried to view a certificate?
Can you also explain how the issue happens, step-by-step? This helps us if we cannot replicate your specific case.
You can share screenshots if that helps. You can create screenshots using something like Snipboard or Imgur and post the link here.
Look forward to your reply!
