Bug in version MCPE 1.16.221

Hello, dear developers. The other day I updated the version from 1.16.210 to 1.16.221 in the App Store. After the update, I logged in to the game and logged in to my Xbox live. After re-logging in to the game, I noticed that I didn't save the Xbox live login. I went again and then went back to the game and made the same mistake again. Then today I was having errors logging in to Xbox live. Please note, because this happened after the version update.
P.S.-I'm playing on an Iphone 5s device.

P.S. 2-below I have attached screenshots of the errors.

P.S. 3- sorry for the mistakes, im rus.
