Error in adding a project - MetaMask Signing

[Iamdeadlyz]

Hi guys,

I'd like to list our project but can't do so since I'm stuck in the signing part.

The console displayed the following errors:

inpage.js:1 MetaMask - RPC Error: MetaMask Message Signature: Error: Not supported on this device {code: -32603, message: "MetaMask Message Signature: Error: Not supported on this device", data: {…}, stack: "Error: MetaMask Message Signature: Error: Not supp…eogaeaoehlefnkodbefgpgknn/background.js:1:141281)"}

index.ts:126 {code: -32603, message: "MetaMask Message Signature: Error: Not supported on this device", data: {…}, stack: "Error: MetaMask Message Signature: Error: Not supp…eogaeaoehlefnkodbefgpgknn/background.js:1:141281)"}

I can sign the transactions on other DApps except for this one.

Any help is appreciated, thank you!
