ayant réinstallé l'application je n'arrive pas à retrouver mon arbre généalogique qui m'a nécessité plusieurs semaines de travail.Je voudrai connaître comment pouvoir le récupérer.
Did you reinstall Family Gem on the same device or on another
device?
On the same device theoretically you should find your
tree, that was automatically backed-up by Google.

On another device it's normal that you don't find your
tree, because it is stored on the previous device.
Family Gem has only a local storage, not a cloud storage of the
trees.
