Regarding Ian's site, it helps map out addresses without actually creating a wallet — clarifying the correct derivation path. But the legacy format asks for an extra /0 at the end.
Default derivation path for Bitcoin.com wallets should be:
1st: m/44'/0'/0'
2nd: m/44'/0'/1'
3rd: m/44'/0'/2'
and so on…
To check the receiving addresses, use Ian's site and add /0.
