If you received the error "Key already associated with an existing wallet” while trying to create the "BCH recovery wallet", please try the following:
Your BCH should now show up on your wallet "Home" page, in the new "BCH Recovery Wallet" you just created.
Although you can manage both Bitcoin Core (BTC) and Bitcoin Cash (BCH)
in your Bitcoin.com wallet app, you must not send BCH to a BTC address and vice-versa.
If you have any problems with recovering bitcoins, please email our support team: firstname.lastname@example.org
To help our support staff, please provide as much information as possible. And remember to include a screenshot of your wallet "Home" page.
