Metamask not showing balance of custom ERC20 token (hardhat)

Question

I'm trying to test a custom ERC-20 token using Metamask and Hardhat.

After deploying my ERC-20 coin and minting some to one of the HardHat default accounts I try to add the token to Metamask. It is correctly able to fetch both the decimals of the token and the symbol, however it shows a balance of 0. (I've verified using Hardhat scripts that the balance of the given account is in fact NOT 0 (balanceOf returns 10))

Implementation of custom coin:

pragma solidity ^0.8.7;

import "@openzeppelin/contracts/token/ERC20/ERC20.sol";

contract BobCoin is ERC20 {
  constructor() ERC20("BobCoin", "BOB") {
  }

  function mint(address to, uint256 amount) public {
    _mint(to, amount);
  }
}

Are you sure your Metamask is connecting to the right network?

And import the test account?
