Hi,
In our backend jira tables, we don't see the Team name getting added. I believe Team name is one of the custom field and the data is missing for good number of Jira Issues with in the backend tables.
I checked in issues table as well as issue_team_history table, I data doesn't seems to be available. There is no specific pattern for the missing team names.
We use Fivetran to load the tables. Appreciate your help.
