Hi Patrick Nilan (@pnilan), thank you for reporting this!

We've confirmed the gap you described: the current source-metricool manifest does not define the facebook_account_timelines or instagram_account_timelines streams, while the other streams from the originating contribution did ship. Since the Metricool API exposes this timeline data, adding these streams is a valid enhancement, and we've escalated this to our team for investigation: https://github.com/airbytehq/oncall/issues/13182

The closed PR #68590 can serve as a starting point for anyone picking this up, with credit to the original contributor.
