I receive the following error message I receive when trying to load 3rd party data connectors: “Your admin restricted access to these connectors.” I pay for several connectors, but free and paid connectors are not loading into Looker Studio.
I think you were experiencing this issue, which is now resolved: https://www.googlecloudcommunity.com/gc/Looker-Studio/Looker-Studio-Community-Partner-connectors-down/m-p/757126#M326
