Third party apps are just missing too many features that I use like chat, voting in polls, live threads, etc. No idea whether that’s Reddit’s fault or the dev’s, but it’s a deal breaker regardless.
The APIs for those features were never made available to devs outside of Reddit, no doubt also a decision to drive users to the official site/app. If they had been made available, clients like Apollo would've been using them somewhere between a week and month after release.
