Can’t find my son by name when I click on “start letter.” My son left for boot camp two days ago, so perhaps he isn’t in the system yet to write to. Fine. I will try again every day until I decide they aren’t going to put him in I guess. But my exploration of Sandboxx has been far from satisfying. There’s nothing that tells me how much letters cost, there’s no guidance as to how to use Sandboxx , and the “help” is only a messaging feature, there is no actual page of FAQs or a user’s guide. I don’t think I will trust it to make travel reservations either, because the test run I made on the travel tab was full of bugs. Tap departure date, get a calendar, choose date I want, then no way to return to the previous screen; it just stays on the calendar. How do I then go back to input the return date? But once when I tried I somehow managed to get both dates in, but I have no idea how, and I can’t do it again. Also, when I did get the dates in and searched for deals, it didn’t tell me what airline I was seeing deals for. Just seems like a junk app. Needs much more work. Most important: USER INSTRUCTIONS!!!
