getting failures on code_verifier after upgrading our File Maker server. Requiring end user to to do multiple attempts and then it is successful. This seems to be intermittent.
I checked the community https://community.auth0.com/t/failed-to-verify-code-verifier/99156 faq but didn’t see the page.
We’re in a pickle. Any help will be appreciated before we open a ticket. Thank you!
