v2.4.0

L'application permet de synchroniser des calendriers apple, mais dans mon cas elle fonctionne seulement pour deux calendriers sur trois. Pour celui qui ne fonctionne pas, après avoir rentré l'adresse webcal j'ai le message d'erreur length=0; index=0 . Dommage ! J'ai communiqué mon calendrier comme ils me l'ont demandé mais je n'ai vu aucune amélioration. Cela dit après 6 mois le calendrier s'est mis a marcher. Ils ont du faire une mise à jour et depuis cela fonctionne !

Developer Response

Can you send us the webcal address so we can take a closer look at it? support-en@davx5.com Thank you!

v2.1.1

La synchronisation ne se fait pas de façon régulière depuis plusieurs semaines maintenant je ne comprends pas d'où vient ce bug

Developer Response

Thank you for the update of the review :) Please make sure the app is exempted from any battery saving mechanic on the device. Otherwise it is killed in the background while it wants to perform a sync.
