Rest API. Creating an issue in Jira failing with 401

Question

We are using OAuth 2.0 (3LO) app to make API calls to Jira Cloud.

We are using the API to read issues and also to write issues.

Using the token created with the oauth flow, we are able to read the issues but creation of the issues is failing with 401.

This was working before and we started observing this 401 behavior recently.

Is there anything changed from Jira SIde?.

Below is the authorization url used

https://auth.atlassian.com/authorize
?audience=api.atlassian.com
&client_id=PUesxfvPz8GruyEQtXyJr7JigCoBRyAW
&scope=offline_access%20read:jira-work%20write:jira-work

This is the error I am getting.
{"code":401,"message":"Unauthorized; scope does not match"}

What is the scope required to create an issue?
Jira APP already has write:jira-work permission.

I don;t have much to add other than to say :

1.  Check the expiration of your token -- especially if you were working before and didn't make any changes.   and

2. don't let a working "GET" call lull you into a sense that you have your token set up correctly.  I've seen REST GET calls work when my token handling was wrong only because I was also logged into JIRA already.

I think  your issue is likely more complex and advanced than I normally run into.

Thanks
