The email format you mentioned should be acceptable when sending invoices to your customers, tclawn_service.

The primary causes for errors when creating transactions often include an unstable internet connection and a buildup of browser cache. Let's secure first a strong and stable internet connection.

If the system still won't accept the email format, let's consider troubleshooting your browser. While cache can speed up browsing, an excessive buildup can cause unexpected behaviors. A good starting point is to use a private browser, as it does not retain cache. If necessary, we can clear cache.
