I downloaded the eight episodes of HBO’s My Brilliant Friend. Six of the eight episodes were assigned an expiration date of 1/14/2019, but two episodes in the middle (episodes 5 and 6) had expiration dates of 12/16/2018. The two episodes with the December expiration disappeared from the list yesterday, as expected. I accessed the available downloads and downloaded episodes 5 and 6 a second time, and this time the expiration dates were 1/14/2019, same as the others. Any idea why there is this strange behavior?
