I'm running into an issue with a SharePoint Task form that has been converted to a Nintex form. In browsers other than Internet Explorer, we have issues with HTML tags displaying inside the Task Description field when opening the task to edit it. Also the Rich Text formatting tool bar only displays in IE. The latest versions of Edge, Firefox, Chrome, and Safari all show this issue.
I have a case open with Nintex Tech Support but they cannot reproduce the issue, so they are not interested in investigating further. I've confirmed that we do not have any Group Policies applied that would effect browser settings. I've also tested in a non-domain joined VM and have the issue. It happens both in Windows and Mac computers.
I've attached a screenshot of a form with the issue with the html tags highlighted. Has anyone else run into this issue?
