Good day
Update:
Council Motion 23 executed sucessfully on Centrifuge on block 123403. The XCM sent to Polkadot to execute hrmp init requests to Statemint, Moonbeam, and Acala was received on block 12028830 but it failed with a FailedToTransact error.
The issue was identified and addressed by @nuno and you can find the explanation here.
A new motion (Council Motion 24) has therefore been submitted. The details of Council Motion 24 are the same as for Council Motion 23 - the issue mentioned above has just been fixed.
