I am still having this issue and agree with information_junkie that it's happening on pages requiring some kind of login/SSO. I've had issues with Microsoft Office (Outlook, SharePoint, etc.) and Google Ads as examples. Every time it reloads, I receive a notification on my Microsoft Authenticator app to approve a new sign-in, but the website doesn't prompt me to log in. Super odd.
This is a deal-breaker for me when using this browser, as I heavily rely on Microsoft and Google apps in my workflow. I hope the issue is identified and solved soon because I love everything about Orion.
