I've got an issue with responsive forms. My external users cannot edit and save forms after migration to SP2019 On Prem. I have an external test account that I am using to troubleshoot this. When I add that test account directly to the root site with full control it works fine. But adding all my external users with full control is obviously not a good solution. Is this a bug with Nintex?
