Hi! I can see this as well. The log shouldn’t appear – but it doesn’t mean anything is wrong. Page 2 is the Global Canvas of your app, and as it has no UI, it’s complaining about that. I don’t know why you would get a whole stream of it, but I reported this bug and hopefully it’ll get fixed soon
I couldn’t quickly find documentation specific to global canvas, but basically it’s a logic canvas that is “global”, that is, started from the beginning of the app and kept running. We use it for global events, like setting something from app launch, or for when we want to have an event we can trigger on any page. I like to use it to set data into app variables to reduce the amount of polling to a database.
