@JudyL if you havent already...since you have Amazon Firestick and YouTubeTv now which only has the main QVC channel ..
you can download the app QVC+,HSN+ ( just hold down your lil blue voice button on your firestick remote and say "QVC PLUS".
The app should pop up with a button on the screen to click on to download. It will then show a web address and a code youll need. Then ts faster to type the web address in your tablet or computer broswer, go to that website and put th code in, easier than trying to toggle around on your tv screen hiting letters but you cam As the say in England boom Bob's your uncle its done.
Its free and if you want to watch QVC main, Q2,Q3 In the Kitchen (special channel), HSN main, HSN2 its all the channels. This is an app like your YouTubetv is an app so you cant toggle between YouTubeTv unless you go out of one and into the other i think.
Once you see how easy it is to download free apps, watch out it can be addictive....lol enjoy.
