I have recently been unable to authenticate using Google SAML with the RingCentral desktop app or Classic app. I do not believe the issue to be a SAML issue as the account being used to authenticate will work in other cases with RingCentral like RingCentral Phone, RC app on IOS & Android.
After some searching I found this blog from Google.
Which explains the behavior I am experiencing with the RingCentral desktop apps previously mentioned. I believe both the RC app/classic are running an embedded version of Electron and would fall in the embedded browser category. I think this may be a wider issue at least in my instance and hasn't been a real problem yet due to SAML being able to have a persistent session, but after log out I have not been able to authenticate again.

My question would be has there been any further reporting of this issue or am I an isolated case?
