Xumo Peacock Subtitles issue

We have Xumo and when we are watching Peacock we cannot remove the subtitles. I have read every other forum on here and have tried all of the suggestions. NOTHING IS WORKING. Subtitles are set to ‘off’ within Peacock. And even if I wanted the subtitles, there is a 30 second delay, insanity. When is Xfinity going to actually fix this problem??
