Why is GoldM futures (Apr Series) blocked for trading

I want to use Goldm futures to hedge some of my SGB holdings but I see that all contracts from Apr series and further are blocked for trading. Why is this so? Having to constantly hedge using the near month contract and roll over will increase transaction costs significantly.

I just checked the Apr series contract and it has good liquidity and OI. Please open it up for trading

We have enabled GoldM April and May contracts for trading.
We’re also reviewing other precious metal contracts, and wherever we see sufficient liquidity and open interest, we’ll enable those contracts as well.

Perfect. Thanks
