I have been using Elixir for about a year and the only problems I have found is the much smaller ecosystem. It's still a niche language. This means you may be the first one to encounter some problems although I have found the community quite helpful. Even if the number of libraries cannot really stack up to Rails the few libraries tend to be high quality. Overall, I find things more explicit and understandable. There's a lot less magic and I find functional code easier to reason about. At the end of the day, every popular language was niche at one time but some people took a chance on it. Maybe Elixir hasn't yet gone mainstream but its a fairly healthy ecosystem with many brilliant, passionate people.
