Good question. third party login sites mostly don't keep me logged in, kick me out, doesn't let me log in, etc.

Give us some real concrete examples. This does not match my experience at all so I'm dubious.

I have trouble with google login (url must be copied into a google tab) and oracle cloud loses my tenancy home region every few minutes (https://i.imgur.com/ZCsepq3.png). Several other examples like LMS's that use O365 to log in must be manually logged in every time

I use both Google and O365 at the educational institutions I work at and both platforms works fine across a wide variety of applications. Strange that you are experiencing these issues.
