Hey there! No- You’re not suspended, however that banner will stick around for a while longer. As you send more emails (and fewer bounces occur) your bounce rate will drop, and once it dips below a certain point, the banner will disappear. The banner isn’t checking to see if you’ve done the steps you’ve described- It only looks at the bounce rate over a recent period of email sends.
In short- You’re all good, and the banner will disappear on its own, and you are free to continue sending out emails (as long as there isn’t a further rise in bounces).
