Hey Seb,
I've just responded to this question on your other post here in the Community. In case you missed it, here's what I said:
"Thanks for reaching out here in the Community! QuickBooks Self-Employed is a program totally designed for solo-entrepreneurs. That means you're in charge of your own bookkeeping, and I'm here to point you in the right direction for help. It's essential that you have access to your BC GST when you need it.
If you're noticing a difference between the mobile version of Self-Employed, and the web browser, try updating your app. To do this, visit the App Store or Google Play store.
The QuickBooks Self-Employed team are specialists in this version of the program, and they've got special tools and resources that allow them to troubleshoot these kinds of issues. I can appreciate that having to use a web browser to create your invoices isn't what you're hoping for. The most important thing to me is seeing that your issue gets resolved quickly and efficiently by our agents.
I recommend reaching out to the QuickBooks Self-Employed team directly to do some further troubleshooting. Here's where you can reach them: Contact QuickBooks Self-Employed.
