Last year the App never worked for me, it was possibly due to bandwidth issues.
It never updated.
Wifi is virtually non-existent in previous years, and as my Le Man buddy is no longer an ACO member, we don't get into their areas with Wifi anymore.
I am a Three customer, so the Feel at Home service works OK for email and Messaging services, and I use a Thee MiFi as well. Neither of these are good enough to stream video in my experience.
