When two wallets are installed, in order to choose which wallet is being used to connect to dapps, you will need to toggle one or the other off in your Chrome extension settings (chrome://extensions). To do this:
1. Click the three dots next to your Chrome profile
2. Click More Tools > Extensions
3. Toggle either wallet off using the slider
4. Refresh the tab that has the dapp open
You can also access an extension's settings directly by right-clicking on the logo, followed by "Manage Extensions". Once you refresh the dapp, it will load the correct wallet.
