I think the forced switch was just postponed a few weeks, probably because Xmas is not the best season for the team to handle unforeseen glitches etc. I also think most users have none or few problems with the app, so if you come across a link to install it, and have the time for explore a new UI, it will probably still work like it used to. I'm holding back because I never change a "winning team" unless I must, and my game works fine.
