Just saw this on a Plex Facebook ad. Use the code SEEYA2021 to get 25% off Plex Pass. Offer expires 23/12/21 @ 23:59 UTC 23:59 UTC on December 31, 2021. (which converts to Friday 24th of December @ 10:59am AEDST).
I'm wondering if this works with the workaround as described here: https://www.ozbargain.com.au/node/666383
