I received this explanation from LG Electronics.
In short, CMore's website does not support our browser and therefore it is not possible to log in and stream via it.
Unfortunately, the browser in the TV is not fully adapted for streaming, and many streaming websites are not adapted for our browser. There's not much we at LG can do about it. For streaming, we always refer instead to the apps that are available to download or are pre-installed. To download apps, you can then do it via the home screen and then among the apps select "Apps" and then there in the app store, you can then search for the app.
If you have experienced that it has worked before, it is because all the data storage was not there before and in the long run this causes an overload the more you stream.
If you are missing apps from the range, it is because the company or service provider has not chosen to develop an app for our platform. If you have comments on this, I recommend that you contact the respective company and draw attention to your dissatisfaction about this and hopefully push for them to develop an app in the future. LG Electronics Norden obviously also works to get the companies to develop the most requested services/apps for our platform.
Currently, I personally recommend getting a Chromecast, Apple TV or hooking up a computer for a wider range of streaming and service
