"Je vais vous envoyer l'adrésse de mon site web" and "Je vous enverrai l'adrésse de mon site web" both should be correct I think, but the program marks the former as wrong. 

In this exercise “I should maybe call the train company” is translated as “je devrai ... “, but “I should really insure my phone” is “je devrais ...” . It’s only a very small detail (and I believe both are pronounced the same, or almost the same, by most people anyway), but why is the future of devoir used in one case and the conditional in the other?

Mon meilleur ami Pierre, qui jusqu'à l'année dernièrer partageait un appartement de deux chambrtrois-pièces avec moi à Paris
