Joseph_A,

What exactly is going to the Intuit Blog supposed to accomplish?  The link you provided arrives at a landing page with generic QB blog topics.  Searching for "INV-43564" yields "no results."  If you are instructing those of us affected by this issue to get updates via the blog, please provide instructions that work.  How about a link directly to the blog thread for this issue?

An update on my ongoing attempts to resolve this:

• my installation of QB 2020 on Mac Catalina was clean from the start.  There were no previous versions (2019, 2018, etc).;
• uninstalling, reinstalling does nothing;
• returning to the permissions settings never shows QB as an option to grant access to;
• manually saving pdf invoices and emailing outside of QB is tedious.

Hope this gets escalated.  Interested to hear from other users if they find a solution (excluding the uninstall, delete old versions, reinstall - which doesn't work for me).
