Insurers must inform us about rate increases or cancellations, but I’ve heard they sometimes don’t follow these rules. Do companies actually respect these notice periods in the real world? Will fighting back through a state regulator lead to real consequences for them, or will it just create more paperwork for me?

Suggest to me some high-yield business savings accounts with better rates or features for exploring a C-corp. I gave a thought to Wealthfront (doesn't offer business accounts) and Live Oak Bank (offers 3.7%). So suggest some other bank options to me.
