Spreadsheet sync not working Session Expired

Hello there, Michelle.

We can perform basic troubleshooting steps to see if it is a browser issue. Sometimes, your search engine's cache and cookies become corrupted, causing problems when accessing websites or opening files. To begin, open your QBO account in an incognito window. It will prevent the browser history from being saved. Please refer to the following keyboard shortcuts based on your browser type:

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

If the private browsing session works, clear the browser's cache, so the system can restart. This task is also possible in other supported, up-to-date browsers. Clearing the cache will reboot the system, allowing you to work with clearing the stocked cache and cookies causing the issues.

We've also received similar cases and reports about this. Know that our engineer is currently working on a fix for it. We appreciate your patience as we investigate this further. I recommend reaching out to our customer support team to add you to the list of affected users.
