/e/ OS S is no OTA update for existing devices with recently versions of /e/ (if i understand that correct), like Manoj wrote in the upgrade list thread:
From time to time i take a look at the /e/ OS apollon image page.
Afaik LOS 19 = Android 12 = /e/ OS S… and LOS 19 is available for apollon: https://download.lineageos.org/apollon
So maybe it is just a matter of time?
