Cette nouvelle version va très mal, elle fait perdre du temps en plus d’être bombardée d’annonces.

Keyboard disappears

Just downloaded and tried first calculation. When modifying some fields in cable parameters the pop up keyboard (on iPhone) appears and disappears again before anything can be entered. iPhone issue or app?
