i had to re-register (with new bin file), but got an sms and the registration "crshed", restarted yappari and registration began again, but sms code wasn't correct anymore and call service shouted russian numbers to me!? first time i heard it...after that i got the message that i have to wait 1390 min (~22 hours)....vie bluestacks and original whatsapp i can login...now, have i wait 22 hours before i can register to yappari or is there a "work-around" ?
