Great suggestions, @ChynnaBlue!
@taginsc2016, The only thing I can add, when you have problems with an app it sometimes helps to look at all the recent reviews to see if others are having problems. I took a look, and I see several complaints but not any matching your specific problems (I could've missed it, though). App developers usually watch the reviews for reports of glitches, so if there are lots of complaints it's likely a new version might be in the works.
I use Apple devices, and my preference is to use the full website version, because I've never been that happy with QVC's apps (sorry, Q). But I can see there are some benefits of the apps.
Best of luck in working out these annoying bugs!
