Most cross-platform solutions are great in the beginning and then the problems start to come to surface as teams grow, requirements change, bugs are harder to track down, code needs to be updated, the next hot cross-platform framework comes along with new promises, etc.
Sure but, these issues come to surface much quicker.
Every time I've started a new iOS project in the past ~2 years, I've reached out to a handful of developers and managers on how cross-platform is going for them. None have been completely sold on it. The ones that are, are the ones that have been doing it for a few months. I've come back around to talk to them months later and they aren't so confident in the decision anymore.
