If you are getting the popup it means the app was already installed (I assume that for me at least it happened with the upgraid to Android 7 since I didn't get it before).
The app is by default enabled, but not actually doing anything (except providing this wretched pop-up). It can only actually do anything if you set it up fully, presumably providing a login and personal details - I don't know, I didn't get that far.
Following the procedure I outlined above will not start the app, simply disable it and hopefully remove the pop-up.
If you decide to go ahead an set it up you will apparently get all sorts of interesting distractions, principally in the form of additional information on your tabled or phone related to someething you've shown an interest in in a programme. Their video shos the example of a character carrying a fashionable handbag, and the viewer expressing an interest in this and getting information about it on their tablet, and an opportunity to buy it. I don't know exactly how this works, and I have no intention of trying to find out: I don't want my TV turned into a shopping channel. I would advise you to follow the procedure I gave - this won't start it up, just cripple it at the first stage of the process.
