Hello,
We have a SharePoint 2016 farm that has a custom master page created for it. When adding Apps, we only get "Document Library", "Custom List", "Tasks". Team collaboration is turned on. It is a publishing site, I have disabled that feature as well as team collaboration, turn publishing back on and then collab no available.
As a random test, I changed the masterpage to both Oslo and Seattle and now the standard set of "Apps" are available to add to the site but not on the custom masterpage.
Content Type is set to "HTML Master Page", but I have tried changing it to "Publishing Master Page" with no success. Not sure where to look from here.
Any ideas?
Nicole
