I think it's less likely to happen at a startup, because there is more work to be done. Larger companies often have some kind of official training (even the boring enterprises). I know this, because I freelance with a training company and often do things like training courses to teach a bunch of companies how to do Material Design.
It takes a lot of time and error to mess around, and some libraries have such immense productivity boosts that it's a waste of time not to do them.
In my case, I once bought an ergonomic keyboard and realized that I was typing the wrong way for years. My typing speed halved for about a week, so I did some 30 min/day training routine until I got it back up to an acceptable rate. But I think that I could actually be typing a lot faster if I bother to practice with it. There are some other things - debugging tools, keyboard shortcuts.
And there are some major things like learning RxJava, Kotlin, Butterknife, or some architecture, which isn't always possible with 30 mins/day, but may cost productivity if delayed and something you want the whole team up to date with.
