I'm simply trying to determine whether this is an isolated review decision
What if it is?
whether other developers of football prediction or fantasy league apps have recently received similar feedback.
What if they have, or haven't?
These are not rhetorical questions. Please explain what you plan to do about it, in material terms.
App Review specifically asked us to answer "Yes" for "Gambling", not "Simulated Gambling". That's part of my confusion. The App Store Connect definition of Gambling refers to betting or wagering using real money (or currency exchangeable for real money), while our app has no betting, wagers, entry fees, cash prizes, payouts, odds, or exchangeable virtual currency.
In your original post:
App Review says that because the app includes "tips, tools, predictions or other information related to real money gambling"
Perhaps random people on the internet aren't that reliable. In hindsight, I think my assessment was wrong. Instead, perhaps "Simulated gambling" would be restricted to a virtual casino or virtual card game environment. In that kind of app, there is no virtual outcome that would have any relation to any actual, real money gambling scenario. Such a simulated gambling app might help people learn individual card games, or make a realization that Orlando might be a better vacation choice than Vegas. But the app would be useless if the user were actually gambling in Vegas.
Your app is actually modelling a real-world, real-money gambling scenario. It could help people make predictions in current, real-life gaming events. Ergo, it's a gambling app.
