I have a fairly significant problem right now... One of my site collections is not allowing me to open task forms because "The app Nintex Forms for Office 365 is out of date":
Going to the site contents at the root site collection level, I see an option to update both Forms and Workflows:
However, following either of these links just takes me to the Sharepoint store, with no option to update (just tells me I already have the app):
In the meantime, all my workflows are broken because users cannot open the task forms. This is only a problem on one of my site collections, I believe because the Nintex apps were added later to the others.
Does anyone have any idea how I can get the update?
