Yes, I got mine today, too, in the app, from Titanium to Platinum.
Sunday, 1 March to Sunday, 22 March 2020. Close enough for government work!
I am personally grateful that the Marriott IT delay of three weeks gave me a chance to get another year of UA Premier Silver status, based upon my Bonv°y Titanium Elite status earned in 2018. (!)
Thank you, Bonv°y IT and FlyerTalk!
