So today emails stopped ingesting from our helpdesk email account, figured it was a token expiration issue, but the token was still valid, tried restarting the server, making sure we were on the latest supported version of php, deleting the oauth2 plugin and re-adding the most up to date one from the website, remaking the shared secret and confirming that every setting outlined in the guide was applied correctly, and it's still not ingesting any emails. It is successfully sending email using the oath2 authorization so I know that the authorization and the app registration is still working and now I just don't know what to look at that could be causing the import to fail, this is with a cron job in place on the system and the auto-cron enabled.
