I had downloaded it but never rebooted to update because I heard about some issues and decided to wait. Now it's saying I'm up to date with Android 13?
Yes the update most likely was withdrawn for people who had not yet installed it due to a significant issue affecting Pixel 6. You're missing absolutely nothing of value on Android 13 in the meantime
I wouldn't expect them to recall it from users who already installed (I think Android downgrades are tricky), but I only downloaded the update and never installed it (never rebooted for it)
It's not impossible. The update isn't set in stone until you reboot into the Android UI. Prior to reboot it can be discarded trivially. Post reboot but prior to starting up the Android UI, it can be rolled back.
It would be interesting to see if it's an actual cloud-controlled recall feature or whether it's something simpler like timed expiry of an installed but not activated update. Haven't dug into update_engine for that. Could also be in the upper updater layer, outside of update_engine.
I've downloaded the update but I have not yet rebooted. Does anyone know how to delete the update package? I'm afraid I'll end up having to reboot at some point because of a crash or running out of battery. Pixel 5a
