I'd head to AVSFORUM.
https://www.avsforum.com/forum/40-oled-technology-flat-panels-general/2974552-2018-sony-a8f-owners-only-thread-56.html seems to note it may roll back on a factory reset then you can block the update.
So yes, folk are reporting issues. Nod to AVSFORUM in their Sony threads.
Has anyone else had trouble with using the Sony Bravia TV remote to control channels of their cable box after the February update? It is like the IRBlaster no longer picks up the channel functions.
