I can see the inconvenience caused you, @David11_2. Please know that we will provide a resolution and give a better user experience about saving your company information in QuickBooks Online.
One possible solution is restarting your computer to refresh the whole program. Next, utilize an incognito window. Log into your second account and save your information there. If this option proves successful, we can proceed with clearing the cache from your regular browser.
Here are the shortcuts to incognito browsers:
Google Chrome: press Ctrl + Shift + N
Microsoft Edge: press Ctrl + Shift + N
Firefox: press: Shift + CTRL + P
In addition, the cache can interfere with the proper functioning of QuickBooks and lead to the absence of tabs and features. Therefore, clearing the cache is necessary to minimize issues arising while using QuickBooks.
