I have no issues getting into the Taycan after leaving it unplugged for days (deep sleep/full off happens after 45 mins). Surprisingly they’ve managed to fix the remote pre-cool/heat function so that it works almost 100% reliably now with the new app. Once I’m in the car the interface takes about 10 seconds to fully appear but the reversing camera can come up immediately so I’m only missing music. Items like Apple Music (native) and CarPlay can take 5mins or so before appearing.
I’ve never had any issues with getting into our 2018 Tesla and it being ready for core functionality — they say that 10 seconds (max) is the golden number for waiting for an interface.
Edit: I should be clear that I think the Taycan has a garbage user interface that is from 1992
