This issue seems to exist on all routes, but my narrowed example is on this route:
/rest/api/3/issue/createmeta/{projectIdOrKey}/issuetypes
I can only use an unscoped key to access that route. If I use a scoped key I get the following error:
"{\"errorMessages\":[\"You cannot create issues in this project.\",\"You are not authorized to perform this operation. Please log in.\"],\"errors\":{}}"
I've created 4 keys with these permissions:
Every key gives that same error. Am I missing something here?
Edit: This doesn't seem to be limited to Product Discovery. I get the same error when accessing a regular Jira project; I also get the same non-error using an unscoped key on that project.
