Windows 10 Comcast Payment Issue

@XfinityDaryl​ Thanks for reply. I am not talking about using the mobile app. I have the newest Xfinity app on my iPhone 12. I am able to pay using the mobile Xfinity app. I am talking about using Xfinity.com on my desktop computer. I have windows 10. I have paid using that method each month for years. When I click pay now after logging in, the desktop goes blank. If I switch the desktop browser, either Edge or Chrome, to incognito mode, login and click the pay now box, it works as it should. Something is not allowing the pay now feature to work. I have cleared, history and cache/cookies. It was working fine until beginning of month when tried to pay the bill. I have know issues paying phone, mortgage, water, utility bill on those various sites…just Xfinity. Thanks for any suggestions. dan

I really appreciate the details you've been able to share. Have you noticed any other functions or windows on our website that are unavailable for you on your desktop? I am checking and creating a log with our reported issues to see if there is something else going on behind the scenes.
