Hi! Does the error look like this at all? [[Bug]: Chrome setApprovalForAll function fails in Metamask for some collections · Issue #18507 · MetaMask/metamask-extension · GitHub](https://github.com/MetaMask/metamask-extension/issues/18507) Can you please confirm what version of MetaMask you are using?

No luck unforately. I get this when trying to invoke `setApprovalForAll` on this contract `0xfbeef911dc5821886e1dda71586d90ed28174b7d` on etherscan or infact on any site which allows this change to happen.

Hey, I’m getting the exact same error. I tried to approve KnownOrigin’s contract to be able to sell a KO token on their marketplace, but I think there’s some issues since they’re being treated as ERC20 tokens (the native KODA token), and not as NFTs - so MetaMask doesnt recognize the “set approval for all” thing. This really sucks. I have tried removing the KODA in the “Token” tab (I have no “Assets” tab), and tried removing all the NFTs (I have 7 KO pieces), adding the 1 piece I want to list etc. But no luck. I just updated my MetaMask, but I also had the error on the last version, but I haven’t updated my Chrome Thanks for assisting me in this! ---

I am also getting this error. I have done the same as Norwegian. Known Origin website says something about a KODA v1 and a KODA v2 contract. And under the contract I can see some people actually approving the SetApprovalForAll I have tried all browsers and all combinations of adding the NFT Following for updates ---

Crazy there is no solution posted after all this time. Seems like no one at MetaMask cares either, probably time to switch to Rabby wallet. Here’s the way to fix it: Go to your MetaMask wallet in your browser not the extension, go to swap tab, change networks to optimism then back to eth. Boom fixed, you are welcome.
