Good news! I can confirm that now new quests pile up even if you don't open the game, but with a catch: I completed all quests, then I closed the game and waited long enough to receive 2 new quests. Then, when I opened the game again, I received one quest and the timer for the second one was at 7:59:xx. So I closed the game, opened it again and a second quest appeared. Also, the timer for the third one was already at 2:36:xx.

So, be sure to clear you queue before going to sleep and in the morning you will have 2 or 3 new quests waiting for you, although not all of them will show up at the start, but they'll probably be there hidden and if you restart the app or complete the first one, the others will be revealed.
