Roku Ultra no longer recognizing 4K

My Roku Ultra is no longer recognizing my TV as 4k and switched to HD only. This happened over the past week. 4k used to work until last week with the same TV and setup. It is not specific to any channels. I have done all the usual disconnect and restart. I have also checked for latest updates (as of Nov 24) and completed them. But the Roku Display type setting only shows 1080/720p and recognizes HDCP 1.4. My TV is 4k UHD and HDCP 2.2 complaint and working with other devices. Please find me a solution.
