The Bitcoin Cash address shown in your wallet uses a modern format called CashAddr. It is distinct to the legacy Bitcoin-based addresses because often the users would make errors and send their Bitcoin Cash coins to their Bitcoin address and lose their coins forever.
Some wallets don’t support the “bitcoincash:” prefix. In that case, you are safely remove this prefix.
To counter this issue, you can use an online free address converter to change your address to a legacy format. You can also go to the Linked Addresses page and link your own Bitcoin Cash address.
