I would like to add my phone number to my ubisoft account but ubisoft has deemed that my phone number "does not respect security standards". I went on ubisoft website to try to look up the solution, i chatted with the live chat and filed an official claim that my phone number is not illigitimate and that I want to play ranked and nobody at ubisoft has reached out to help or get in contact or at least tell me why my phone number is unable to be added.**I also really hope that your recommendation is not "just add a different phone number." That is what the person at the ubisoft live chat told me. This is unhelpful for one very simple reason. I do not have any other phone numbers. the whole point of making ranked rainbow six siege accessible only if your phone number is added to your account is so that cheaters are deincentivised to cheat as they only have one phone number. I am just trying to play some ranked r* with the boys please help
