The number shown behind the error is the time you have to wait before your account is unblocked for verification. If there is no number, you will need to contact Whatsapp to unblock your account, without mentioning the fact that you are using Wazapp.\

You cannot switch from N9 Wazapp to N8 whatsapp then back to N9 Wazapp and expect it to just connect. From what I understand, Whatsapp recongises your IMEI.

I switch phones too. So whenever I switch back to my N9, I will delete the Wazapp account before opening Wazapp so that it can re-register.

the number indicates the time in what, minutes hours? Thanks for your help. Edit: now i get "fail too many". This is after waiting about 12 hours since last try.
