XBox One Dashboard Preview has made my console almost completely unuseable

So I've been in the preview program for three or four months now and a couple days ago my console updated to the new dashboard. ever since I've had constant networking issues, crashes and bugs. Most of which were solved with a reset, but today my console
will not connect to XBL despite the network and multiplayer tests in the network settings saying that everything is good.

I'd really like some help on the issue as soon as possible.

Thumb stick drift on elite controller

I purchased an xbox one elite console in december. I began experiencing drift in the right thumbstick on the elite controller that came with it a few months ago, It's gotten to the point where the controller is almost unuseable for some games. How do I go
about having this repaired/replaced?
