Issue controlling playback

I have had my 4 channel Tablo for about a month, and am having issues controlling playback of recorded OTA shows, using a new Samsung TAB E & Chromecasting to a Chromecast dongle.

Playback looks great as recorded at 1080. Only occasional lag.

However, if i use the skip forward arrow to skip an ad, the show starts over at the very beginning every time.

Also, the show used to play simultaneously on the tablet, and I could pause & restart from there. Now the first Frame stays on the screen & there is no control of playback.

Please let me know if there are settings or updates that will fix these annoying flaws.
