I think Dave posted a couple of months ago, that latest Android versions (9+ or sth like that)
use a scoped storage where /sdcard/DroidScript refers to something completely different. /sdcard/Android/data/com.smartphoneremote etc.
And in order to not loose your projects after uninstalling app, you will need to back up them. If you changed your phone Android version recently, that could be the problem. But I think what you did is irreversible, except for the case that you haveade a back up or your projects or house a device with reversible storage actions and history... Which I think you don't.
