Unfortunately Facebook are now actively banning people using WA+. It appears they're determined to eliminate all third party app rather than just select ones. Doesn't bode well for a replacement for Mitakuuluu ... Positive note is that they don't appear able to detect WA+ when it's run in Alien Dalvik. So until such time as it stops working, I guess I'll be using the now end-of-life WA+.
