Is Polygon zkEVM on mainnet?

Excuse me, could you please clarify if the Polygon zkEVM is currently deployed and operational on the mainnet? I'm interested in understanding if it's available for users to interact with on the live blockchain environment, and if there are any known limitations or challenges associated with its implementation. Additionally, I'd appreciate any insights into the timeline for its launch and any future plans for enhancements or updates. Thank you for your time and consideration.
