Receiving Sepolia chainId when buying NFT on Mumbai network from OpenSea Testnet

[ngocpd-1250]

Describe the bug Receiving GETH chainId when buying NFT on Mumbai network from OpenSea Testnet via WalletConnect (It works well with MetaMask.)

My session namespaces: ["eip155": WalletConnectSign.SessionNamespace(chains: Optional(Set([eip155:5, eip155:80001])), accounts: Set([eip155:80001:0xf24ac6dc44c8ed6ce036714973ef4c993fb8296f, eip155:5:0xf24ac6dc44c8ed6ce036714973ef4c993fb8296f]), methods: Set(["eth_sendTransaction", "eth_signTypedData_v4", "personal_sign"]), events: Set(["chainChanged", "accountsChanged"]))]

SDK Version

• Client: Swift
• Version: 1.6.10

To Reproduce Steps to reproduce the behavior:

1. Connect your wallet with open-sea via WalletConnect
2. Go to this link: https://testnets.opensea.io/assets/mumbai/0x2631aec1028bed281506b0521a49fd55ba2a90f9/2
3. Click Buy.
4. When I buy NFTs on Mumbai from the show link, occasionally I receive the chainID of GETH in the request.

Expected behavior Receive the chainID of Mumbai in the request.

Thanks, forwarded problem to OpenSea team

@flypaper0 I don't think this is a problem with OpenSea. I have tried using Android and didn't experience this issue.

@flypaper0 @alexander-lsvk I reproduce this problem by changing supportedChains to: let supportedChains = [Blockchain("eip155:5")!, Blockchain("eip155:80001")!] https://www.dropbox.com/scl/fi/i7gkxp2mx06thwbbxmb5z/reproduce_bug.mov?rlkey=d6bz7smemp5kajcjbb5sx8t1w&dl=0

Please help me check

Currently, Opensea has changed the required chain to Sepolia, but I am still encountering the same issue. When I purchase an NFT on Mumbai, I am still receiving the chainId of Sepolia. (It occasionally occurs)

let supportedChains = [Blockchain("eip155:5")!, Blockchain("eip155:80001")!, Blockchain("eip155:11155111")!]
