I use a hardware TAN generator though I also have a banking app as a fallback on my Lineage OS phone. If I ever buy a Pixel it's only to install Graphene OS on it.

The next target after Russia loses against NATO will be China actually. And then Iran, North Korea. But you'll get a total nuclear exchange well before, so it's academical.
So likely next proxy is Moldova, Romania, Georgia, Belorus. Poland is also a possibility, but not at first. Unless Belorus, but then we're at tactical nukes stage already.
I can't imagine using a TV. None of them are wall sized and I don't have the space. Pull down screen fits the bill.
