It seems like NetSuite may have broken something today with OAuth2.0. Anyone else dealing with it?

We have a plugin that gets a Oauth2.0 token back but they all started failing around 10am today, but when  I tested Postman it's working.    Our dev noticed that the plugin (which hasn't been updated recently) has been using RS256 but my postman script is using PS256.   When I updated my Postman to use RS256 it failed but PS256 it's working.

I don't see any notes from Netsuite about this change and saw someone else on downdetector talking about the same issue.

Finally heard back

Your concern might be related to an ongoing 24-hour Test Window for End of Support for RSA PKCSv1.5 Scheme for OAuth 2.0. In order to resolve this, you should replace the previous RSA scheme with the new RSA-PSS

(see SuiteAnswer <https://suiteanswers.custhelp.com/app/answers/detail/a_id/101101> to generate using the new algorithm). To add, the said previous RSA would be deprecated on March 1, 2025.
