Thank you for bringing this to our attention, marian. Let's perform some troubleshooting procedures to determine if this is a browser-related concern.
Your browser's cache stores files on your computer to speed up website loading on your next visit. However, it can become outdated over time, causing issues with accessing websites. To get started, we have to open your QuickBooks Online (QBO) account on an incognito window. Doing so 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 a clean slate.
