L1 staking - "Failed to approve amount" immediately without MM approval

[EpicChicken]

I'm trying to stake ETH on L1. As soon as I enter an amount and click the "Approve amount" button on the gateway, I immediately get a "Failed to approve amount" error - but I never receive an approval request in Metamask. I was able to bridge ETH and OMG to L2 and stake both successfully a few days ago, so this only seems to happen to me on L1.

More info: Metamask version 10.1.1 Tried with both Chrome and Brave browsers, both fully updated No hardware wallet associated with this MM wallet

Here's the error. I'm getting this regardless of the amount I try to stake. "Max amount" shows the correct amount of ETH in my wallet, and MM is currently on L1:

Chrome console log when I try to stake:

Same issue here. Using brave browser with a ledger. Had no issues bridging to L2 or staking (OMG) on L2.

Yes, you are right. Bug was introduced when changing to new system for simplifying approval flow - fixed in pending https://github.com/omgnetwork/optimism/commit/fde3451ec3d4c975c83cf55dc784bf6a256494dd. Thanks again for helping and reporting issues!
