Some delayed RICs stopped in production.

Our some delayed RICs stopped updating prices in production.

To request delayed prices, we used to add "/" before ticker but now some tickers have stopped updating prices.

some ticker examples .AAVBG00 , AAYWS00.

But after we append D-* to the ticker, (i.e. D-AAVBG00). they started updating latest prices.

Is there anything changed recently in delayed tickers?

If Yes, can you please provide change notification published by Refinitiv, We need to take necessary action on this.

Thanks in advance.
