Ms Buffy,
Might I suggest a Chromecast device. From Harvey Norman/Officeworks etc. They are very popular. They plug into the HDMI socket of your tele.
I have 3. One built into the tele, one connected to the tele and one for the overhead TV projector.
Apps in “smart” TVs are a “one off” version for that particular tele. They do not get updated, and will eventually stop working with “version not compatible” or just won’t work. A Chromecast device will update itself so you always have the latest version on the device. Chromecast devices are made by Google.
A Chromecast device does NOT have any apps loaded into it. You use your phone/tablet to control it, so you always have the latest version of the app.. You can use it from your computer as well. Get the 4K Chromecast device if you have a 4K UHD TV.
You use, say, theFreeView, Iview or SBS on Demand, 7+, 9Now etc, Netfilx etc, or any other app, including Youtube. There is a FreeView app for your phone/table.
It costs you nothing to try these apps (including FreeView) on your phone to see how they work etc. This gives you the ability to control play/pause/volume etc from your phone/tablet and search functions using the phone/tablet popup keyboard, rather than silly up/down arrows to navigate an on TV screen keyboard.
Wherever you see the below icon on your computer or phone/tablet, just tap it, and it will automatically use your TV by tapping it.
