Ever since I updated to iOS 15 on my iPhone 8, the Nissan EV app has completely stopped working.
As soon as the app opens, it bounces me over to a web page, and displays the following error:

An invalid operation was detected against this application.
The application cannot be used after an invalid operation is performed.

The URL of the page is:
https://ncsrsweb.its-mo.com/manipulatio ... ion=15.0.1

Is this happening to everyone or just me?
I have contacted Nissan UK about it, but they haven't got back to me yet.

I'm using a 2015 Nissan Leaf, and never had the problem before the update.

I'll just point out that Apple is infamous for "moving the furniture" in their IOS's without telling anyone. There will probably be a patch in a month that fixes it, and they won't tell anyone about that either. In the meantime, your only option may be a temporary rollback.

Nissan have finally updated the app. So it works now with iOS 15.
