I understand how important it is for you to use QuickBooks Online (QBO) seamlessly in your day-to-day operations, FPCNS. Let's go through some troubleshooting steps to get this resolved.

First off, may I know which browser you are currently using? Intuit recommends using Chrome for the best experience possible. If you are already using Chrome, please ensure you are using the latest release by going to the Chrome menu, selecting Help, and then About Google Chrome.

Next, ensure that your operating system is up-to-date and you meet or exceed the System Requirements for QuickBooks Online.

Additionally, add Intuit as a trusted site for your browsers to prevent your browsers from potentially blocking site content.
