SAML config files

I've removed SAML authentication in the application , but the application still appears to be redirecting to obsolete Application ID in the Azure portal with the following error...

AADSTS700016: Application with identifier "X" was not found in the directory "X" this can happen if the applicationhas not been installed by the administrator or the tenant.

the application identifier is the original, this has now changed, but believe this must be being passed back from the SolarWinds application even although SAML is disabled in the SolarWinds application.
