I have used the mobile app for about 6 years, very few problems. I didn't realize that the app had an auto save, I just use the save button every few minutes. I have not had time to try 3.6 yet, but 2.6 is working fine. I don't think 3.6 will go online this year, seems to be too many problems. I don't mind trying to help anyone with questions about the mobile app, I am pretty much self taught, but feel I know it pretty well. If I don't have distractions, I can be in and out of a normal 2000 sf house in 30 - 45 minutes, sketch complete, photo's arranged on the pages in order with the descriptions, page 1 of the 1004 mostly complete and if there are repairs, they are in order in the notes tab, ready to transfer to the desktop with a few clicks. In my opinion, the mobile app saves me at least an hour or two from the paper and clip board days.
