LinkedIn authentication appears to fail on iOS & MacOS Safari as an Auth0 error page is displayed saying
Oops!, something went wrong. There could be a misconfiguration in the system or a service outage.... However, refreshing the browser page causes our application to display as if the authentication was successful.
The Auth0 log console says there was a successful login for a LinkedIn connection. There is no problem on iOS Chrome, or Android Chrome or desktop Chrome and the connection Auth0 console LinkedIn connection test. There is no problem with Google or Facebook authentication. On MacOS the developer console displays:
https://instnt-live.eu.auth0.com/login/callback?code=AQSMR2Wg0QJRs8AdkH6dkGfQbz3ebSjeFQ0RAU3dwDDP8fHIrLYMhNRSMxM05bT1R090wtdRA998Dotu84wvmIGxCEBUlL4m8BxDxaEN9fyTJc2Ev7N9UF9DIa8oUApfWkdSDPVQJLlX1cgjwQ0&state=TCZcDBWiQSmreRAkrLlq6hvF8zr-HSch [Error] Failed to load resource: the server responded with a status of 400 (Bad Request) (callback, line 0)
Any idea what could be causing this?
