HI: Not sure how to answer this but we do need more information. I have an older version of the Android app, so this has not happened to me. Maybe that someone using the newer version has an answer.
Did you attempt to upload them to the website from your device, or did you have the device (Android) set to upload automatically?
When you go to your Dashboard, are the photos in the section MY PHOTOS. If so, they uploaded already and you can begin transcribing them. If they are not in MY PHOTOS, then check the actual cemetery page to see if the photos are already there? If you just click "TRANSCRIBE" the engine should go to the most recent photos you took, if they are in the transcription queue.
There is a possible alternate explanation to what happened to them. One mistake that I made and a number of other beginners have made, is to take a bunch of photos without checking to see if they will upload. My first time out I unintentially had my settings so that the photos uploaded to the "cemetery photo" section of the webpage, instead of the individual records. If that has happened, the pictures you took will show up in the window in the upper part of the cemetery page, If that is the case, reply back here for more explanation./information.
