I'd also feel the same way when a button is missing in my QuickBooks Online (QBO), @kikiviolet.

I'll lay out some troubleshooting actions to get the button working again.

First, ensure that your existing QuickBooks Payment account is connected to your QBO. If it's already linked, but the button is still not showing up, try to access your account using a private window. Too much stored historical data from the browser causes discrepancies that affect the view and performance of your QuickBooks.

You can use either of these keyboard shortcuts to open an incognito window, depending on your browser:

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Shift + Ctrl + P
• Microsoft Edge: Ctrl + Shift + N

If it works, you can return to your original browser and clear its cache, not the cookies, for a fresh start. You can also use another supported, up-to-date browser to narrow down the results.
