Has any one else had issues with auto logout and loosing all their info they spent an hours on, saving document then page logs out loosing everything ?

Hello there, @marcel6.

I'd like to ensure that you'll be able to utilize QuickBooks without any issues, so you can save your documents successfully.

Sometimes unexpected behavior in QuickBooks Online is caused by the stored data in the cache. Accessing your account using a private window is a good place to identify if it's a browser-related issue. This can often fix such hurdles.

If it works fine, you can go back to your regular browser and clear its cache. This removes the unnecessary files, which may lead to the problem that you've encountered. It also prevents this issue from occurring in the future. 

You can also check out this article to learn more on what are the browsers that work best in QuickBooks Online: Find out what computer and browser you need for the best QuickBooks experience.

Know that you can always get back to me if you have any additional questions. It would be my pleasure to help. Have a good one!
