xfinity stream app support on Samsung Frame TV

We have a new Samsung Frame TV and use their remote (not Xfinity remote). When we go to SAVED shows, it is not showing all of the shows (only one shows but upper right-hand message says there are 3 shows recorded and DVR is 19% full). It is very random....sometimes they appear but most times they do no. When we watch from another TV using Xfinity remote, all of the shows appear in SAVED section of the application.
