Crashes on start on my wifes iPadAir and iPhone 5c but works perfectly on my iPhone 6+. All are using the latest version. Please delete the french reviews, they dont belong here. It is infuriating seeing them. I have no idea what theyre saying. Typical french rudeness and arrogance. Theres no mention of passbook in the description, so stop complaining its not there! Id like to be able to make the text smaller. Its too big.
