I picked my car up last Saturday and have not got the update yet. I would rather get it sooner than later so I don't get spoiled with the old UI. My wife got the update on her Y and doesn't really care for the new UI.
Have to ask, have you rebooted after getting the release? Many issues that seem to come with a new release are fixed if you do a normal two-scroll wheel reboot. I always do one as soon as the software finishes loading.
this whole release seemed to take much longer than normal to settle down.
Usually they can get wide rollout figured in a couple of versions, but this one took eleven versions to figure out - from 2020.48.35.5 to this release. Which seems nuts for all that work to just be "minor improvements".
TLR - delay in rollout is normal at this time of year.
I couldn't edit this post - My car got the update this weekend, but interestingly the last time there was this amount of delay for me was V2020.8 back in March last year. In 2019 there was a period of three months (Jan-Mar) when it also took 30days between releases. A pattern methinks.
