we recently updated our SharePoint 2016 on-premise Farm from:
CU Update: August 2018 to June 2020
Nintex Workflow: 188.8.131.52 to 184.108.40.206
Nintex Forms: 220.127.116.11 to 18.104.22.168
Since this updgrade, we can't edit any forms using the content type "Schedule and Reservations". Before the upgrade, this was possible.
" Error - Cannot use Nintex Forms for content type : Schedule and Reservations"
What we checked:
- The content type setting "Read only" is set to "No" in our CT-Hub and has not be changed.
- In the sites, where the content type is used, we changed the settings from "Yes" to "No".
- unfortunately this makes no difference.
Forms of Calenders, using the content type "Event" can be edited as normal.
