I'm sad to say that this really shouldn't be surprising, as it's been a trend with EA for years and years now. The thing is, it's still disappointing every single time.
Our friends at Nintendo Life have gone through FIFA 19 on Switch, and they've noted that a handful of Ultimate Team features from other versions aren't included here. The missing aspects include:
- Division Rivals mode is not included
- weekly FUT champions event and Squad Battles are not included
- daily and weekly challenges are not included
It's pretty safe to say that these features won't be implemented in a future update, so Switch owners will just have to do without.
