Thanks. I think you may be referring to the desktop version rather than the Android version.
As I mentioned, there is only one decimal place for the still image duration. Inputting anything other than a single decimal place means none of the other digits are visible. That's why I asked if any more digits are used or tossed out. There is no shift key on a tablet. Well, there can be if you have the virtual keyboard open but that wouldn't be the case here. You can add an entire folder of images to the media window but then, as far as I can determine, you have to drag each one to the timeline indvidually. Not sure there is a 'storyboard mode' on the Android mobile app.
Well aware of the numbering issue, thanks.
