When I checked my Trello App in my phone, I was not able to access it immediately. Instead, I was prompted to log-in. So, I did, but I noticed that from the last board that I was using, which is what I usually use, all of the cards disappeared except the last card that I was using. I checked all my other boards and the cards there are intact. The missing cards are very important to me. I have compiled it over the years and now it is all gone except for one. What might have happened? Is there any way to retrieve them?
