APPS-04233

Xfinity’s services, without exceptions, are generating errors. The APPS04233 is only an example. I Asked Xfinity’s useless Ask Xfinity, it did not allow entering an error code other than what was preselected, then it presented two types of error categories neither started with Apps. 
Xfinity’s technician called me this morning for his scheduled appointment at 9 am, he could not find Perry St in San Francisco and he did not provide any answer when I he asked him to describe his location on 3rd street for me to meet him on the street as he requested. Nevertheless, I waited on 3rd st for 5 minutes looking for an Xfinity vehicle. After I got home he called me back to tell me that he finally found my building. I wondered aloud about the use of Google maps or any such silly navigation aids, he said something about his gps. 
when he finally got to my place he asked me what help I needed from him. His visit was arranged by xfinity upon their advanced technical support failed to resolve the primary issue of failure to deliver Netflix’s videos in Dolby Vision and Dolby Atmos. The only issue that I have been trying to resolve using x1 Primary TV box for the past two years or so. I told him that the newly delivered tv box, the third in a few weeks, is failing to deliver Netflix as stated above. I noticed a blank look in his eyes and stopped myself to ask him about the scope of his visit after telling him that there is nothing wrong with the tv box other than the Netflix issue. Another blank look in his eyes. I asked him do you know what Dolby Vision Dolby Atmos videos? He responded no. I proceeded to ask him about his assignment this morning to which he also responded no. I respectfully stated that there is nothing he can help me with. He left immediately with a huff. 
The technician who came to my place two weeks earlier to solve the same problem he insisted to check on his car and never came back. I guess he did not know what I was talking about because he spoke no English. 

that only covers maybe 10% of my problems with xfinity and I can still tell you much more. But I don’t want to burden you with more fables 

I have to tell you one more thing; I filed a complaint with the State of California Attorney General and I hope he reads my comment I submitted to the PUC of San Francisco online Public Hearing last month studying any needs to evaluate the service quality of Xfinity 

@Again provided a link to a solution which in  sumary is (I had exact same issues with my 3 Xi6-A boxes.  Tried everything, tv's would boot into a blank black screen instead of last channel I was watching before turning it off.  I also had APPS error trying to press the c button and watch sports events.  I finally had a good tech troubleshoot and resolved by , 'Needing to update the IP module of the boxes'.  This fixed it 100%.  I'd reach out to Xfinity support (I used chat fyi) and just ask them to 'Update the IP module of the boxes.'  Good luck!)

the staff at the Xfinity’s store claimed no knowledge of anything about IP tv it only exists on student subscription they claimed.

I have seeked every aspect of help from xfinity and the only available help renaming is to file a complaint with the state of California and my statements are still valid
