I am having the exact same issue!!!
Let's perform some browser troubleshooting steps so we can get rid of the error message and get you back to business in no time.
To start with, let's pull up and open a new private window of your browser. This can help us check if the spinning green circle is related to your browser or not.
From there, let's go to the QuickBooks Online Login page and enter your login credentials. If you can log in and access your account successfully, you can clear your browser's cache to optimize its performance.
However, if you still received the error message, let's switch and use a new browser application. After doing so, log in and access your QuickBooks Online account from there.
Meanwhile, if you still have the issue after following the troubleshooting steps above, I'd recommend contacting our Customer Care Support. From there, someone can help you investigate this further and file a report if needed to do so.
Lastly, I'll be also adding an article that'll help you improve your browsing experience while working in QuickBooks Online: Why is my QuickBooks Online Slow?
If there's anything else that I can help you with, please let me know in the comment section down below. I'll be always around ready to help.
Are you using Safari 11 or later? If not, this could be the reason why you’re experiencing this issue. Older versions of this browser are already discontinued and no longer compatible with QuickBooks.
For additional information about this, please refer to this article:Discontinuing support for Internet Explorer and old Safari versions.
Aside from Safari, you can also use Google Chrome or Firefox. These are also supported browsers and updates own their own automatically.
Though, if you’ve followed these requirements and still having the issue, I’d recommend reporting this to our engineers.
To do so, you can reach out to our phone support team. They’ll be the one to escalate this for further investigation.
Since you’re unable login and the only way to contact support is inside QuickBooks, you can contact the Desktop support instead. Once you’ve reached them, ask them to transfer to the right department. Here’s how:
Stay around if you have other questions.
It only happens when I'm clicking on links outside of the homepage. For example, on the homepage, dashboard, etc, no flashing occurs but if I click on an internal link such as invoices, that's where I get the screen flashing and spinning green circle using Safari (which is up to date btw). I tried it on Chrome, no issues at all.
If you have any other ideas LMK.
Thanks for the additional information, TOYSTRY.
It's also good to know that you're using an updated Safari. The Safari 11 or newer is the best to use in accessing the QuickBooks Online.
I'd suggest contacting our Customer Support Team since you keep on receiving the same behavior. They'll be able to look into the cause of this. You can follow the steps by MikiD on how to reach to them.
In the meantime, you'll want to continue using the Chrome. This is just temporary until you'll be able to access it using the Safari.
You're always welcome to post again. I'm looking forward to assisting you again.
