Stable coin interest rates on binance

I see that Binance recently introduced locked staking for UST and has a 30, 60 and 90 day period , each having their own personal quota limit. Does anyone know what the limit is for the 60 day lockup period? It says it is " sold out" and I am not sure when they will be available. Is there a way to get a notification is a staked product is available?

Also is there any other stablecoin on binance that gives rates close to the ones in Celsius or
other lending platforms?
