Chrome OS is similar to BETA software from the 90s only there has never been nor will there ever be a stable or semireliable OS.  It is absurd just how badly the basic features of this OS NEVER work reliably.  You can't use google drive within Chrome file manager.  You can wait 24 hours after recently uploading and your docs still won't be shown within file manager - USELESS.  Instant tethering with your Android phone NEVER works.  They update this pathetic OS every month or so and what do they do with that opportunity?  They add more features with ZERO reliablity.  Chrome OS is pure Google garbage from a monopolist with ZERO financial incentive not to destroy your productivity with CRAP Software.  It really is that bad.
