Has Voyager 1 left the Oort Cloud?

Excuse me, but could you clarify something for me? I've been hearing a lot about the Voyager 1 spacecraft and its journey through space. I'm wondering, has Voyager 1 actually left the Oort Cloud yet? I understand it's been traveling for decades now, and I'm curious if it's made it past that mysterious and distant region of our solar system. If not, could you give me a rough estimate of when it might reach the Oort Cloud, and what challenges it may face once it gets there? Thank you in advance for your insight.
