Wifi Calling with T-Mobile 635 & WP8.1 Update 1?

Has anyone installed the WP8.1 Update 1 on their Tmo 635 yet? Is your wifi calling still working?

I get sums, mms, and phone calls but when I answer them no audio on either side of call

My calls and texts are working with no problem. I updated last week.
