Almost one year later, version 4.3.21 and still no Zerotier. Maybe not that important, but don't claim it in the documentation then. False expectations, make one loose all trust.
GL.inet with fake claims ? If SFT1200 is fraudulent, then why buying the more expensive devices, just to get more disappointments?
GL.inet should adjust their documentation, or fix the SFT1200. Zerotier missing is a minor issue, the totally unstable/unusable wifi uplink connection is a major issue.
