Didn't see this page previously as I don't look at the ID4 section often, but just to add, I have had OTA 3.0 since a day or two before ukwizard I think and it is working well. Scheduled charging is working perfectly. The system in my car takes very slightly longer to boot up but is noticeably quicker once running (it was never a slow booter though, to avoid scaring people - it used to boot up fast but be laggy in use). Lane assist now does a better job of actually keeping you in lane on a motorway rather than letting you get slightly over the line, and not zigzagging quite so hard - although still annoying on other roads. The navigation is a big improvement for long drives with chargers - it gives you estimated arrival % and required departure % at each stop, and integrates the live availability data from wecharge in to the nav. Obviously you can can see SoC and outside temperature in the driver's display too.
The only negative for me so far is that I can't use online voice control. There is a bug in the app that is preventing me from enabling permission for the car to use it. I have seen a few other people with the same. Given that online voice control for navigation was laughably poor before the update this is not a big loss, but since the whole point of part 2 of the OTA update was to improve it, I was hoping to try it out.
I found the installation process ok but there were more steps than I was expecting even having read the instructions. You should definitely read the instructions so you know how to set up a profile after part 1 completes (and ideally allow 20-30 minutes in the car to do it).
There have been a small number of bricked cars on people's driveways but none in the UK that I know of, overall the programme seems to be going a lot better than 2.4 I think. Think they must be reaching the end of the 1000.
Oh, I saw someone reporting that the send-location-to-car function in the app now works repeatably and quickly...not for me!
