I am unable to get the "multicurrency" flag to save after I switch it on in company setup. How do I know what the problem may be or fix it?

Try opening your QBO account on any private/incognito browser.

et's resolve the error you're having with your multicurrency, @nolaheale.

The problem you're having when trying to save the changes you've made for multicurrency can be caused by the piled-up cache in your regular browser. It stores temporary internet files from your browsing history. As it collects too many files, it can cause some issues in your account.

To fix this issue, I recommend signing in to your QuickBooks Online account using a private browser. This helps to isolate the issue since it doesn’t store data in the cache. 

Here are the following keyboard shortcuts: 

• Safari: Command + Shift + N
• Mozilla Firefox: CTRL + Shift + P
• Google Chrome: CTRL + Shift + N
• Microsoft Edge: CTRL + Shift + N

If this works, you can clear cache and cookies to fix issues when using QuickBooks Online. Restart your browser right after. If the issue persists, you can try using other supported browsers such as Firefox, Google Chrome, Safari, or Microsoft Edge.
