I'm not sure how we missed your post. I'm sorry! What TiVo software version does your Roamio have? Software version 20.5.2 (or later) is required. Have your TiVo account settings recently changed? Within the My Account section of your online TiVo account, click Change DVR Preferences. Is there a check mark in front of Video sharing and Enable video downloads? If yes, uncheck the boxes, click Save, and return to DVR preferences to recheck them. If no, check-mark the boxes for Video sharing and Enable video downloads and click Save. Then, force a connection to the TiVo service by going to Settings & Messages > Settings > Network > Connect to the TiVo service now. After this process, has the Cox On Demand launchpoint returned?
No, unfortunately those steps didn't make the Cox On Demand launch point reappear. I called the cable card support line and was informed this is related to a known issue with On Demand for Tivo that is currently being worked-on. Before I hung up, the rep confirmed my cable card still was still provisioned with the correct codes.
We do have an open alert related to Cox On Demand for TiVo devices, so I'm sure the tech you spoke with had this alert in mind. However, I don't believe what you are experiencing is related. My supervisor has a TiVo Roamio, and has not lost his Cox VOD launchpoint.
Have you gone through all of the steps I mentioned yesterday? Page reference: https://support.tivo.com/articles/Troubleshooting/Cox-On-DEMAND-Troubleshooting.
I tried the steps listed in the Tivo Support Forum you mentioned and the Cox On Demand launch point did reappear! However, I have not been able to successfully open the app on my Roamio; whenever I click on the launch point, I receive a V301 - App Currently Unavailable - message. I tried rebooting the box several times and forcing several successful connections to the Tivo Service over the past few days, but the message / issue persists. Is there anything else I can try to get the app to open? All other applications work fine - Netflix, Youtube, Hulu, etc.
