A. If the app restricts usage to one account at a time, consider creating a secondary account with a different email address. This way, you can switch between accounts by logging out of one and into the other. Make sure to keep track of your login credentials for both accounts.
B. Check if the app has a multi-account feature in the settings. Some apps allow you to switch between accounts without logging out. Look for an option like 'Add Account' or 'Switch Account'.
