Not sure why he thinks the option is gone.
I am not supporting his post, just clarifying that it could depend on whether your android has updated. When I tried on a Samsung tablet, using FBS appeared to be gone. When I checked the early access version, where it was confirmed as being at one point, I was unable to use it there as well.
There are so many different mobile platforms, versions of software, and settings on personal devices, it is possible for some people to still observe it after others have viewed it as no longer being available. I think it is a matter of time before it is unavailable on all platforms/devices. That's my guess. good or bad, it is what it is...
