While it is true that Whatsapp has not released an API and does not condone the use of these, or of third-party libraries for Whatsapp, I've never had the problem that you mention the numbers lock but I will take it into account and appreciate your contribution.
Wakati ni kweli kwamba Whatsapp ina iliyotolewa na API na havumilii na matumizi ya hizi, au ya mhusika wa tatu maktaba kwa Whatsapp, Sijawahi kuwa na tatizo kwamba unaweza kutaja kufunga idadi lakini kuchukua katika akaunti na kufahamu mchango wako.
