I had the Vectron Connect App working for nearly two years with a BMV-712 Smart monitor. Then this week, I changed the chassis (car battery). The unit needs to be re-paired but the pin does not work as it wants the PUK code. Well after two hours to disassemble the battery compartment to get to the physical device and see the code, I cannot enter the alphanumeric code. I found on the previous community messaged that it is possible to get to an alphanumeric keypad by clicking on "the three little dots" to the right of the product description. My IPhone 7plus does NOT show the damn dots, nor does trying it on my wife's phone. I have wasted six hours on this and am really disappointed. Can anyone give me advice? Thank you.
