QuickBooks so, so SLOW. VERY FRUSTRATING ie time taken to Log in

I understand your frustration about your experience with QuickBooks Online, fishcreekfnc.

I suggest using incognito browser when logging in your QuickBooks to rule out the possibility of a webpage issue. Private browsing doesn't store local files or cache.

Use these keyboard shortcuts based on the browser you're using. 

• Google Chrome: Ctrl + Shift + N
• Safari 11 or newer: ⌘ + Shift + N
• Mozilla Firefox: Ctrl + Shift + P
• Microsoft Edge: Ctrl + Shift + P

If it works in incognito, clear the cache of your regular browser. Doing this helps QBO to function more efficiently. You can check out this article that will provide more information: Clear my browser cache and temporary Internet files.

If the steps above will not work, you can use supported browser as alternatives.

For more details, you can read through this article: Why is my QuickBooks Online slow? It provides information on how your internet browsers and mobile connections can affect the performance of the program.

You can bookmark this link for future reference: Troubleshooting browser problems. It contains solutions on how to resolve when you encounter issues visiting Intuit sites. The guide is from another region, but it also apply to your version.

I'd appreciate it if you could update me by leaving a comment below. I want to ensure that everything is taken care of for you
