I'm a Diamond-level contributor but have used KVS Tool only occasionally and had never tried to use the mobile tool until a few days ago, when I tried to search for non-award availability on a particular airline in my preferred class of service. Got a message that the current version doesn't allow this and that I should upgrade to the latest version. Went to the upgrade page and it said latest version also doesn't include availability, must use the "KVS Tool Mobile Companion". So I went to my Ipad and followed the instructions for signing on to the mobile tool (email address plus a password that is the ten-digit "S-number" for KVS on my laptop) but got a message that this is an incorrect username and/or password. Tried again several times, checked to be sure email and S-number were correct, same result. Filled out a web-based email form detailing the above and asking for help; the next screen said I'd get an email response within 24 hours. That was three or four days ago, but I have not yet received a response. I'm running out of ideas. Do I really need to go to the airline site and do multiple dummy bookings/seat map checks to get a rough idea of availability on various days during my time period, or have I been missing something in my attempts to access the KVS mobile companion? Thanks so much for any suggestions.
