We have been moving to Nintex Responsive forms for all our mobile and tablet users. We use SharePoint Online and most of our users have the SharePoint App installed on their phone. Apparently, Nintex Responsive forms will not open via the SharePoint App OR if you have the app installed on your phone. So when a user receives and email notification (from Nintex Workflow) with a link to open the Nintex Form, it does not open and you then have to select "Open In Broswer". In addition, if a users goes to a SharePoint list via the app to create a new form and clicks on "+ New" it opens up a SharePoint list and NOT the Nintex Form.
Has anyone else had this experience or have any tips or tricks. The Nintex Mobile App is ok if you want to create a new Form, but you can't use it to open an existing completed form.
