Plasma Bridge not working.

Plasma Bridge not working.

I'm trying to move 7400 MATIC from Ethereum main chain to matic network via the plasma bridge hosted on

I am using metamask with no ledger integration, as recommended. I have about $100 of ETH on the wallet and the estimated gas fee is about $40.

When I try to confirm the deposit, the window shows that the transaction is "approved" but can not confirm.

When I try to confirm, nothing happens, the metamask wallet doesn't ask me to sign.

I just get a red message at the bottom of the window. It says "execution reverted".

NOTE: I am using the most current version of Windows, google chrome browser, and metamask extension. No VPN.
