That's pretty awesome. I consider giving up my phone every now and then, but I am too weak. Props to you for actually doing it.

>But on a supposedly secure banking app?! What the actual fuck?!!!

Yeah, it's a pretty normal practice, unfortunately. There's trackers on all sorts of shit you'd think is private. I even found one on a major pharmacy brand's COVID test appointment scheduling and results page a while back that was leaking patient data and made national news. It's just depressingly normalized.
