Hello there, FMA. Let me share some help regarding this matter.
As I've checked here in our system, there's no reported issue regarding sudden logging off with the QuickBooks Online (QBO) account. To isolate this matter, I recommend it's best to use other supported web browsers or private browsers to rule out any browsing history or cached files causing the problem. Here are the shortcut keys for accessing private browsers:
Google Chrome: press Ctrl + Shift + N
Mozilla Firefox: press Ctrl + Shift + P
Microsoft Edge: press Ctrl + Shift + N
Safari: press Command + Shift + N
Furthermore, you can also access our self-help articles to see any related posts that you can use in future transactions.
