As a developer myself I’m not sure if I would trust any application to safely handle a configuration that has become invalid due to a breaking change, especially not an app that is still under active development! Better safe than sorry.
Immich has completely replaced Google Photos for me, love it!
My only bugbear is that it is updated very frequently (what a nice problem to have!) which in my case requires a manual once-over of my docker-compose file every time in case there are breaking changes.
Something to note: Tesla has two vehicle APIs, the Fleet API for commercial accounts and the Owner API for individuals. This change currently only impacts the Fleet API.
If you are an individual owner who accesses your vehicle data from the Owner API (usually via a self hosted tool like TeslaMate), this does not affect you. Yet.
