I noticed they did "something" and forced certain outdated versions (eg 2018) to comply with Intuit ID requirements since June. Afaik, you don't need to upgrade your existing version (i.e QBD 2018) to comply. Several members of our team are running QBD 2018 Premier and have had no issues with this requirement. Try installing your QBD 2018 on another computer and open your files. When the program asks for your Intuit ID credentials, be sure to log in as the Primary Admin to continue.
