I thought I was the only one, but apparently a couple of note 20's haven't been able to use Google pay. I'm one of those and it is annoying. I'm able to use Samsung pay, but I've always preferred Google pay. Hopefully this fix this soon!
it'll come up with an error message/ large red exclamation point on my phone and it'll decline on card reader...I thought it was just me, but it recently read on article stating that this is actually happening to a few other people too :/
