Danny, this is not an issue related to a specific model as another person noted. It affects all users who have the televisions with built-in Roku that have the "Live TV" or "Antenna Channels" app/input. This would include ALL televisions embedded with Roku which are brands such as TCL, HiSense, Toshiba, and so forth.
October 12, 2021: The guide/app worked fine, although the antenna channels lacked any type of station icon, it was ok, as shown in my video here: https://youtu.be/skGQPMQoawo
*November 10, 2021: The guide/app had been updated, and antenna channels now had icons that reflected their network, this version, is what I believe most of us considered the 'perfect' version, there was no reason to go any further, as shown here on November 15, 2021: https://youtu.be/I3gMy7pN7uc
(In between these dates, there was also another bug where the station guide had issues with identify correct station, this bug seems to come and go every since)
August 25, 2022: An update was issue that added that faulty 'quick guide' "update", no one likes this, no one wanted this, and it's never worked properly, again on all models of these televisions, as shown here on a video I did on August 25, 2022: https://youtu.be/yv8w-gevgIE
August 29, 2022: A further update was pushed through, that removed the 'quick guide' and restored the version from November 10, 2021, once again back to the perfect guide as shown here, I think someone knew that the quick guide was faulty and rolled back the update: https://youtu.be/N8w2x5akAa0
November 2022: Another update push through that had that brought back the faulty 'quick guide', again a terrible idea, this is funny because it was rolled back, then pushed back again with no a single fix.
January 25, 2023: Updated again, this time, the antenna stations logos are altered to appear with gray boxes around them, some channels not affected, on ones that are, you can barely make out the station logo anymore since the logo has been shrunk to fit into a useless grey box that serves no purpose, this is probably the second update that really has destroyed the functionality, I plan to do a video on this soon, but was hoping it was something that would be fixed by now.
....And now.... January 30, 2023: A 'Promoted' Channel randomly appears in the antenna channels lineup that is another truly annoying and useless 'feature'
....As you can see, that is why we are all upset with the 'updates' that really have degraded our televisions and experience with Roku, I was a firm believer in Roku having recommended my family and friends to the platform, but with all these issues lately, not anymore with all noted above.
*I have six TCL Roku televisions, all from different years from 2014-2022, same issue on all of them, other friends and people on these forum using products like the HiSense Roku television all have the same problem.
