I find the Nissan Connect app pretty unhelpful for my 2019 Leaf - it's very unreliable and seemingly only works when it wants to. I had been using the EVA Leaf app very happily until Nissan changed the API (whatever that is) and it no longer worked. I know there was a security reason, but it still leaves me without a remote reading of my battery charge (which is what I primarily wanted.....the stats are interesting, but the battery charge is necessary).
I could go full-info and get the LeafSpy Pro app and leave the OBD II always plugged in, but it seems like using a sledgehammer to crack a walnut. Then again, the information on LeafSpy Pro might be a good thing anyway.
