This morning (before the 8.1 update) I noticed that I wasn't connecting to wi-fi calling. I went into settings and noticed the feature was turned off....I hadn't turned it off. I got an error message when trying to turn it back on. I thought maybe T-mobile had disabled the feature pending the 8.1 update. Since updating I can't turn it back on either. I searched on here and see the notes about not being able to have both wi-fi calling and the ability to take calls on another device enabled simultaneously....but that's not my problem. Anyone else having this issue?
Here's the screen that pops up when I try to turn it back on.
