Cannot disconnect from PayPal Donations in Test Mode
The workaround is to edit the database. Removing the option_value of give_paypal_commerce_sandbox_account in wp_options will remove the connection so another account can be connected. There will be a warning "Warning, your account is not ready to accept donations.", which doesn't affect anything - but the fix for that is removing the option_value of give_paypal_commerce_sandbox_account_errors in wp_options
After fixing the issue, ensure to use a PayPal Sandbox Business Account to connect.
