I have noticed 2 issues affecting my xbox 1 after 2 specific console updates. If this is happening to me, I assume others as well.
Relating to update OS version: 6.2.12998.0 (xb_rel_1506.150601-2200) fre which was supposed to improve party chat functionality has resulted in poorer performance. Party chat disconnects randomly (reported elsewhere in forum) and frequently
does not transition from game chat when joining into a party. It generally shows as being in the party but game chat remains active and it requires multiple attempts at moving between the two activate party chat.
Relating to update OS version: 6.2.11785.0 (xb_rel_1411.141104-1838) fre which provided the restart now function, I have never been able to use it. Instead of restarting and power cycling, the console just shuts off. On the assumption that others are also experiencing this, I request that these be examined and address in a future update/patch.
