web3.eth.net.getId() does not work on the mobile version when my app connect with the network Id:97 (BinanceSC Tesnet)

My app has problems with web3.eth.net.getId(), does not work on the mobile version when it connect with the network Id:97 (BinanceSC Tesnet)

All works correctly with the navigator plugin.
Other networks, f.e. Rinkeby, works in mobile version.

```
MetaMask: Received invalid network parameters. Please report this bug. Object { chainId: "0x61", networkVersion: undefined }

JsonRpcEngine: Response has no error or result for request:
{
"method": "net_version",
"params": [],
"jsonrpc": "2.0",
"id": 2652298086
}
```

Start by reproducing web3.eth.net.getId() on the mobile version with network ID 97 and compare it with the navigator plugin and Rinkeby behavior. Inspect the net_version request and the reported chainId 0x61 response; done means the mobile call returns the expected network ID without the invalid network parameters error.
