In the midst of recording, had to restart Tablo because it had dropped off the Wifi and neither AppleTV nor iOS app would detect the unit.
Restarting fixed the problem with the unit showing up, and the in-process recording resumed automatically. There were now two recordings for the event.
When I attempted to watch the first recording I could not reliably scrub forward or backwards. I could attempt to scrub backwards and about half the time it would work as normal. The other times it would look like it was scrubbing to the right place but playback would not start and the playback scrubber UI was hollow as if there was no content on either side of the new position. Exiting the recording would resume playback but the problem persisted.
The second half of the recording worked nominally.
