What's weird about this? Banking apps (and my company by the way too; they also do not allow phones with root used in the company network since it's a security risk) have high security standards.

OK. I tried that. Super SU deinstalled itself, but my banking app still says "Rooted device detected".
I think you'd better flash stock firmware with odin or change bank, lol. Mine doesn't bother me cause I'm rooted
