Connect App returning 401 Unauthorized for /search

Hello,

A user that successfully installed our connect app is receiving 200 responses from /rest/api/2/project/search and /rest/api/2/field but 401 Unauthorized from /rest/api/2/issue/{issue_id} and /rest/api/2/search. The connect app has requested and has granted READ and WRITE scope. Is there a workflow on the Jira Cloud admin side of things that could restrict the access the Connect App has to view issue information? Is there any thing else that could explain this behavior?

Thank you!
