You can only connect one wallet to your Crypto.com App account at a time, as connecting more than one DeFi Wallet to the same Crypto.com App account is not supported at this moment.
If you have imported the same wallet (via the recovery phrase) on multiple devices, you will be able to connect the second Crypto.com Wallet (on a second device) to your Crypto.com App account, but this will disconnect the Crypto.com App from your first Crypto.com Wallet.
How can I connect a different wallet when I have multiple wallets on DeFi Wallet App to the Crypto.com App?
Assuming that you have already connected a wallet, e.g. Wallet 1, to the Crypto.com App, in order to connect a different wallet, e.g. Wallet 2, to the Crypto.com App, you will first need to disconnect Wallet 1 from Crypto.com App before you initiate the connection for Wallet 2.
Here are the steps to disconnect a wallet from the Crypto.com App:
Go to Settings menu
Tap on “Crypto.com App” under “Connect to Crypto.com App” section
You will arrive to the next screen where you can see the following
Tap on the [Disconnect] button and confirm to disconnect
You will then be redirected back to the Settings menu
After you are done with disconnecting a wallet, you can then initiate another connection to the Crypto.com App. You can pick which wallet you would like to connect to the Crypto.com App as shown below.
