drop down menus for customers and Product/service are not working

Hello, @mtbplastering.

One reason this happens is due to a browser issue that causes functional glitches. May I know if you receive an error when this happens?

For now, let's try refreshing your web browser to ensure you are viewing the up-to-date information, and log in and log out to reset your session with the QuickBooks server.

If both dropdowns are still not working, let's try a different QuickBooks-supported web browser and clear Intuit-specific cookies to help refresh website preferences that might be causing problems when you use QuickBooks.

Feel free to leave a comment if you have any questions about QuickBooks.
