fnuxx , via OnePlus 8T , Nov 8, 2020 : why no ota oxygenos for 8T KB05AA North America and no 8T device on support&download page yet?
Cervantes , Nov 8, 2020 : Hi What version of oxygen do you have ? have you bought the phone from a carrier ? the update zip is uploaded to the support page after all the phones got the OTA
agsbond007 , Nov 8, 2020 : Hi, I personally am using the EU one, but people I know with International unlocked variant, KB2005(Not the T Mobile variant), have yet to get the previous 11.0.2.3 update. There are a lot of people on XDA, OnePlus Discord channel and all, if you look. Plus, OP8T got 3 updates in total, as of now. But not even the full zip of the first update is in the softwareupgrade page of oneplus.com. In fact, there is no page for OP8T in the softwareupgrade page of oneplus.com. Moreover, the latest update for OP8T (11.0.3.4), even though the release announcement clearly says that it's for EU, IN and NA variants - only the IN users are getting the update. No EU or NA users got the 11.0.3.4 update yet. Regards.
