Dont update!

After update it crashes everytime I try to checkin. I am on iPhone5 and it still does that. If you are on the road and with no access to your mac/PC make sure you check in beforehand as this version will not be able to checkin. I sincerely hope they will fix it immediately!!
I cant even get boarding pass on this.. Please do not waste your time with issue.
