[General] ChainId as int is wrongly converted to hex / Provided chainId "280" must match the active chainId "640"

Environment

Mainnet

Provide a brief description of the functionality you're trying to implement.

I have raised an issue with Metamask where the latest version of the Android App (7.1.0) appears to have a bug whereby it takes the chaind as int eg: 280 and converts to hex: 640. Here is a link to the open issue on MM's github page: MetaMask/metamask-mobile#6787

This has an obvious impact on zkSync testnet and mainnet, but I doubt that it specific to zkSync. It is possible that this a bug in my own code but I think it is unlikely since my code owrks on desktop and iOS and the problem began immediately after the upgrade to v7.1.0.

I raise the issue here because others in the zkSync community may be facing the same issue.
