This may be a basic question but does SLM always need to be connected to WiFi? I was working on it from a plane and strangely couldn't see any info in my Show, and I am about to play my first gig with it and don't want a disaster if the venue doesn't have WiFi.
No, you do not need an Internet connection to view your info in the app. If you're still seeing a problem, please submit a help ticket:
