No SAML Login button on login page

Nextcloud version (eg, 18.0.7):
Operating system and version (eg, Ubuntu 18.04):
Apache or nginx version ( Apache 2.4.29):
PHP version (eg, 7.2):

The issue you are facing:
I enabled and configured the SSO and SAML Authentication plugin. I go to the login page and it’s the same as before. There are no additional Identity Providers to choose.

Is this the first time you’ve seen this error? (Y):

Steps to replicate it:

  1. Fresh Install
  2. Install SSO SAML Auth plugin
  3. Configure Identity Provider with our IDP sertings.
  4. Open Incognito window, go to Nextcloud site, default login screen.

did you solve it? and if yes how? we have the same problem

I am also having this problem.
It was showing when I was testing but not anymore after reconfiguring
