I wonder if I will muddy the already clouded waters...

Whatsapp wants just OFFICIAL apps made by them for IOS, Windows Phone, Android to work with their server.

Yappari and other apps like it, get away with being unofficial by not revealing that they are, well unofficial. It is a bit like the arms race of the old cold war.

The point being made to nagarendra and others is of you get banned then yappari cannot help you. You need to put your simcard into a phone running one of the officially supported OSs, and use an official app to request the unbanning.

As coderus wrote: "You need to register number with official client, if it failed you need to press contact support button, it will open email client with filled body with some data. you need to add details about blocking status, tell him you never used 3rd party application and only using this android/windowsphone/etc. device."

Posting again asking for help from within Yappari is pointless.

Most of us using Yappari don't get banned. A good rule of thumb with an unofficial client is, if you see some or other suggestion that the server not talking to your device, DO NOT TRY AND TRY AGAIN to connect. Get to this thread and 1) READ and 2) if not noted, post asking if anyone else has the same problem and 3) do not hector the devs for a solution.
