I just subscribed to streamsaver plus. I am unable to activate apple tv plus after about 2 hours of trying. any ideas

I cannot activate apple tv plus even after talking to 2 support people from xfinity.  I had no problem with Netflix and Peacock.   I have added Apple tv app, then deleted, and added back several times.  tried taking a picture of the qr code and doing it that way.  cleared cache out of phone and tried. no luck.  tried to do it via computer with no luck
