I have created a private oauth app for pagerduty using new oauth2 authentication using this docs
[https://developer.pagerduty.com/docs/app-integration-development/oauth-2-functionality/](http://doc link)
Suddenly yesterday all my old access_tokens expired and I couldn’t use it anymore.API started throwing 401 status code. so I had to create a new access_token. Are there any limitations in the oauth2 app if it’s not published. https://developer.pagerduty.com/docs/app-integration-development/publish-your-app/ (doc link for publishing app)
how did my old tokens stop working and I didn’t revoke tokens from oauth app.
