Xfinity stream away from home on Roku and Fire Stick

So i found a thread that was talking about this but as usual i could not post to it, so i am starting a new one. I have been a Xfinity/Comcast customer since before they were Comcast. I pay well over 300 a month for their services, but maybe not any longer. I am currently working about 850 miles away from my home so we are currently living in our RV, i have no cable access here so I have been using a firestick, i had Xfinity app loaded onto the stick which gave me access to my shows i had recorded on my dvr box at home everyweek. Worked great, about 2 months it quit working, so i install the xfinity stream app because the other app is no longer available (and yes i downloaded it originally straight from xfinity website). Well guess what the new app doesn't work, says i have to be on my home network. Got out my Roku, it doesn't work either. Now since it worked before on my firestick for well over a year it has to be something with the new stream beta app, although nobody at the support can tell me what, you wait 45 minutes to talk to somebody that has no idea other than what is on their checklist. So is Xfinity going to fix this or am i going to drop them and go to the BBB for false advertising. Stream anywhere does not mean in the confines of my house.
