I appreciate you getting back to the thread. I see you are encountering the same issue again about the shortcuts that are not working. I'll share information about this matter.

Before anything else, have you tried using a private browser? I suggest doing so. This way, you can identify if it is a browser-related issue this time and can proceed to your clearing cache. However, if the problem persists, it is best to connect with our QuickBooks Online Support, as it may require assistance from our Customer Care Team. They have additional tools to pull up your account and do a screen share to confirm the issue.
