We had configured SSO on our Pega 7.2.2 using ADFS and SAML2. (It had worked with two hotfixes.)
Recently we upgraded our PRPC from 7.2.2 to 7.3.0 and since then I see "Unable to process the SAML WebSSO request : The Response did not contain any Authentication Statement that matched the Subject Confirmation criteria" message on Pega page after trying to log in. The SAML request/response seems normal but those are encrypted.
