Update for original issue:
Seems after two months Roku team has almost completely fixed the original issue of missing Halo episodes.
However:
Season 1 Episode 8 “Allegiance” is not listed now.
I’ve been keeping up with fixes/changes… saw all episodes get listed, but then requiring Paramount and Showtime subscriptions, then going back to requiring only Paramount but missing the original missing episodes again, to finally almost getting it right… but missing Episode 8.
New season has started, please get this fixed.
