Getting error when trying to delegate matic on https://staking.polygon.technology/

I am getting the following error: Cannot read properties of undefined (reading ‘0’), which happened yesterday.

Happens on the final step. I lost my gas fees a dozen times already trying to stake. Can someone provide feedback on what i am doing wrong?

Have you tried clearing cookies, cache, and reloading the page? You might also try a different RPC.

Also, are you sure you are connected to mainnet and not the testnet?
