We do not have any plans to share around a preview for Nintex for SharePoint 2019 at this time. Should this change we'll get in touch with you.
Hi Lisa Tam,
Is there any sort of ETA on when Nintex Workflow & Forms will be released for SharePoint 2019? I know that 2016 came out around 4 months after the release of SPS2016 - will 2019 be a similar wait?
