Hi everyone!
I just took my AP1 2015 MS85D to the service center to have the latest update pushed to my car. But they told me that they wouldn’t be able to do that because I was already on the latest update for my MS which is weird because other AP1 cars have the latest update.
I’m on 2018.50.6
There isn't a single "latest" software update for Tesla vehicles, or even all Tesla vehicles of a given type (such as AP1 Model S). Years of crowd-sourced understanding the rationale behind why some vehicles get updates before others has not proven successful.
There sometimes can be an issue where an update gets "stuck" or somehow fails to apply, and in that case service center or other tech support might be needed. If you're drastically behind the curve, that actually might be worth an inquiry. But at this point, most AP1 cars are still on 2018.50.6 just like you (according to the TeslaFi firmware tracker).
