Great, we can't wait for the update!
We saw that the app tries to fetch 200 assets at a time and the payloads were too big. We were able to get it to start syncing by deleting all of the editable fields the Jira app settings, but we really want those extra fields. Hopefully there can be a setting to say how many assets it fetches at a time when doing the syncing. The more fields you add to the fields list, you may have to reduce the number of assets it fetches at a time. It would also be helpful if we could choose to only sync assets that were in the "Active" state.
