May I know what error message you've encountered when trying to send the invoice? This will help us determine the appropriate troubleshooting steps we can take, Andrea.
In the meantime, we can perform some troubleshooting steps to determine whether the issue is related to your browser. Start by logging in to a private browser, this will not store cache files that can cause lag to a web-based program. You can follow these shortcut keys:
Google Chrome: Ctrl + Shift + N
Mozilla Firefox: Ctrl + Shift + P
Microsoft Edge: Ctrl + Shift + P
Safari: Command + Shift + N
If it works, return to your regular browser and clear its cache to refresh the website's preferences. You can also utilize a supported browser as an alternative.
