There’s no good reason not to switch and it takes only a few minutes, but if you don’t feel like switching definitely at least email PNC about it.

I recently sent PNC a note that I was switching for more competitive rates (capital one), they told me to call customer service. I did not feel like calling customer service, so I moved all my savings to my capital one. Two weeks later I have an email from PNC saying my new savings interest rate is 4%. So yeah idk just message them lol
