@jschmidt7 Is a tenant where you already had it installed and can’t see it? Or never been installed in that tenant?

It was a tenant that we already had them install. Nintex Support helped me with a URL. Seems short sighted that the new forms is not available but this one is no longer available for download easily.

@jschmidt7 The issue with not being able to install the app was not expected and Microsoft was rolling out a fix, it should be complete at the end of the month.

@leighburke , Is this issue resolved? 

I cannot see Nintex forms for O365 in my apps and I cannot add it to the new site. I have used it in other sites and it is still active.
