Hello again,
Having the mobile app option for completing working in QuickBooks Online on the go can be a great asset. I'm also glad to see that you've been using the option Save and share link for your invoices from the browser, and it makes sense to be looking for that option in mobile too when that's how you're used to communicating with your customers. I'd be happy to help with this.
As I mentioned, QuickBooks Online's mobile app can be handy for on-the-go access to your books. It comes with many of the basic features, such as invoicing, expensing, and viewing your bank feeds. There are, however, some limitations to keep in mind when working through the mobile app. One of these limitations comes with how the invoice can be sent to your customer.
While it's possible to email, export, and even print an invoice from the mobile app, when it comes to sending the invoice, the option available is email. Therefore, if you need or would like to send the link to your customer instead, I recommend working in a browser. You can even try working through a mobile browser to do this.
I invite you to submit feedback about how you'd like to see this option so that our product development team can consider it for future updates. You can leave feedback right in the app. Depending on which app version you have, it should be in the settings area. Otherwise, you can leave us feedback while logged in via browser with these steps: How do I submit feedback?

I hope this helps clarify the options. Have a great week!
