Right, that makes sense. My knowledge about the whole tracker is fairly limited.
I’ll ask Abyot at some point how he handles that

The ID might not be the same across instances? So if it needs to work across instances that won’t work?
Sure, but you don’t have any guarantee about anything like that, not name, age, etc… nothing is created for you. You need synchronised metadata to make this work properly across instances (if you actually need to know what is the name etc, I don’t think we have any special handling of that in our tracker apps, just display associated attributes)
