First, sorry for my english, I'm french and not very good in english, particularly to write it.
Since few days I have the same problem. I went in holydays without computer so I use the App. Fist days no problem. I log in draft and I transform it in real log with the app few days later (when I have phone network). But since 3 days, I'll do the same: draft and few hours later real log. But I lose all of them! On the app I saw during 48 hours the yellow smiley and I can't log it again but I can't see the log on the website and after all disapear...
Not funny at all !! I hope this bug will be fix in a very short time
