The question is answered, right answer was accepted
Good afternoon.
My company wanted to activate two devices this morning but when we signed them up in the sigfox backend we made a mistake of contract and, later, instead of editing what we did, it was to erase those devices and to register them again. But at the time of giving it to ok we get a message that says "CRA rejected the modem ownership transfer: Invalid PAC code: <PAC> (please contact your device supplier to obtain this code)".
I have already seen that the PAC is for single use, but the device where the module is sent always sends the same PAC. What should we do to fix it?
