I am confused. It seems like the updated point release is out as per the tweet. But I have yet to see anyone with AP2 or AP1 acknowledge here that they have received it.
Many people have been reporting getting an update, in the Firmware 8.0 thread. According to Tesla Firmware Upgrade Tracker Web App 2.52.22 has been rolled out to about 10-15% of the reporting base of AP1 cars, and AP2 cars were getting 2.52.36 and 2.52.20.
It's not a wide release, like most Tesla updates. Usually they release an update to around 20% of the population, then slowly trickle a few more updates to slightly newer versions, and then push out a widely released version a while later.
