DASH mixing takes a very long time


Months before, Evan made a big deal out of Masternode blinding
There is NO issue with Darksend, in fact the new masternode blinding system is quite impressive.
Masternode blinding was announced with much fanfare. All the usual suspects were so excited!


But then it was delayed

************ Please Update To 11.2.22! ****************
- DS Speed Improvements : Darksend should be lightning fast now on mainnet. We're going to delay the implementation of masternode blinding because there's two separate mobile wallets that are in the process of implementing Darksend and the reference implementation needs to be super stable during this period of time. Once we have the mobile wallets done (which should have Darksend and InstantX support) we can move back to improving Darksend.
So now that both mobile wallets have been implemented, why hasn't the working Masternode Blinding been implemented into DASH?
Why is it still taking 20+ hours to send a simple anon tx with DASH 
??
