[quote]App stopped authentication to steam and no longer functions. Redownloaded app and issue persists. Problem started with this weeks update. Please advise.[/quote] After a while of testing, I upped the app cache in settings and am now it's working?

Having similar issue with XBOX. I sign in with code sent to me from Microsoft. It shows my userid properly, then bungie asks to Accept or Decline. I click on Accept and after a while get message that says "Objet has moved" and brought back to sign in screen. Tried multiple times, uninstalled the app re-started and re-installed and same thing happens! Started doing this last week.
