dmwinsd, Thank you for bring this to our attention. If we haven't done so already, we do want to check the TV Activity Screen by pressing;
(50.0,52.0,54.0 remote) Options>TV Activity>See if there is an available tuner
(40.0 remote) Red Tab button> TV Activity> See if there is an available tuner
If there is, we want to update the guide by making sure that tuner stays open so the receiver can begin the process. You can also clear a tuner and Hard Reset the receiver by unplugging it for 10-15 seconds and plugging it back into the wall and allow the guide to update that way.
Thank you for bringing this to our attention. This has been a reported issue to our Engineering Team that episodes are missing the "new" tag in the guide. They are currently working on finding a resolution to this issue. We are able to add your account to the report for the Team, if you can send a Private Message with your account number and 4 digit PIN. This will let them know that you are experiencing the same issue. For instructions on how to send a PM, here's a link: https://communities.dish.com/t5/Communities-101/How-To-Send-a-Private-Message/td-p/15039
In the meantime, we have found a work around that may resolve the issue. You will place all receivers in standby for 30 minutes. This process will initiate a guide update. Let us know if this work around was successful for you. Thanks!
