Welcome back to the Community. I trust that business is going well on your end. It's important you're able to use the program the way it was designed. Don't worry, I'll be glad to point you in the right direction so you can achieve your QuickBooks goals.
To get started, I recommend clearing cache and cookies on your browser. Clearing cache and cookies is a great way to clean your browser allowing it to work more efficiently. Here's an article that shows you how to do that: How to clear cache and cookies. If this doesn't work, I suggest using a private/incognito window to see if that works instead. Try this out and let me know what happens. In case this issue persists, I encourage you to contact our support team so they can assist you further with this. Here are our contact details:
