The biggest problem I have with quickbooks online is constant hanging of the service and it constantly ignores request to create new suppliers or customers.

I appreciate you getting back to the Community, aquaspring.

Thanks for bringing this to our attention. To further isolate the issue, I recommend accessing your account in a Private browsing window first to verify if this is caused by the system or your browser.

Once able to open a private browser, kindly access your account again and try to create new suppliers or customers.

If it works, to ensure this doesn't happen again, it's a good idea to clear the cache of the browser you're using.

I'd be glad if you can update me know how it goes. I'm always here to help out.
