I appreciate you for joining the thread.
Before anything else, may I ask if you've already done some basic browser troubleshooting on your end? If not, I'd recommend doing it to ensure this has nothing to do with your browser. Sometimes temporary internet files such as cache and cookies can speed up the performance of your browser. Too many of them can also affect your experience when using QBO.
To start the troubleshooting, you'll want to access your company in an incognito or private browser. You can use these shortcut keys:
Chrome: Ctrl+Shift+N
Firefox: Ctrl+Shift+P
Safari: Command+Shift+N
Once you're in, try turn on AMEX again. If it works and it does not show, you can proceed to clear your browser's cache. Refer to this article for the steps: Clear cache and cookies to fix issues when using QuickBooks Online.
I'd also recommend using other compatible browsers if the issue persists. Refer to this article to see the list of compatible browsers in QuickBooks Online: Other browsers.
Lastly, if you're still unable to get through this, you can reach out to our Customer Care Team. This way, they can assign a representative and conduct further investigation to determine the root cause of the issue. Refer to this article for more information: QuickBooks Online Support.
In addition, you can check this handy article to help you manage your bank deposits inside the program: Record and make bank deposits in QuickBooks Online.
Let me know how it goes by leaving a comment below. I'm determined to get you through this situation. Stay safe, and have a nice day!
