1. Open the app,
2. Connect to an unsupported network
3. Press on the 'Wrong Network' button

AR: Message says: 'Please connect to a supported network in the dropdown menu or in your wallet.'
But when select a network in the dropdown, nothing is changed: no request to change a network is sent to the connected wallet.

ER: it would be nice to remove 'in the dropdown menu' from the Wrong Network message
OR change its text to the currently used:
