Hi All,
well after giving a fight against Shared Contacts, I'm posting this error I'm getting with the shared contacts folder. After sharing the contacts, the user receives the acceptance mail and it goes smooth until you go to the contacts tab and press the shared contact you have received. If pops a Network Service Error Alert and the details are the following:
