Welcome and thanks for posting in the Community, @usermorgan.
To check if this is a browser-related issue (cache and cookies), have her sign in to QuickBooks Online (QBO) using a private browser (incognito).
Here's how:
- Press Ctrl + Shift + N (Google Chrome).
- Ctrl + Shift + P (Firefox).
- Control + Option + P (Safari).
If it's successful, she can return to her default browser and perform a clear cache to refresh the system. However, if the issue persists, have her use other supported browsers.
