Serious and potentially very annoying bug has been found in latest WhatsApp version. The bug allows previously blocked contacts to send messages and to see user's online status ("last seen").
Quite many people are familiar with the concept of permanently blocking annoying contacts who harass them via various online services. And just like most other such services, WhatsApp has easy ways to block unwanted contacts from contacting you.
However, now the previously set blocks have been, for unknown reason, failed and messages from previously blocked users have managed to come through.
WhatsApp itself hasn't announced the problem yet, but there seems to be an easy fix for this annoyance: unblock the previously blocked people and block them again. This seems to solve the problem.
The bug seems to be affecting both, iOS and Android users.
