We're sorry to hear about this issue. Did you use the other suggested browsers (Safari, Microsoft Edge, and Google Chrome) to see if it makes a difference? Also, try clearing the browser's cache and cookies and let us know if that helps.
Are you still experiencing this issue? If so, please let us know when you have been seeing it. Have you recently installed any third-party plugins or extensions on your browser? Try to disable the firewall first and see if that helps. Otherwise, you can also update your firewall and, after rebooting the device, check how it goes.
If the above steps don't help, I'd recommend reaching out to and working with our support directly as a next step. They can be reached here: https://adobe.ly/3ZQ4cYG
