Right now, it’s looking like it could not have worked in older versions of AppStudio either. The problem is the statement which imports the database chokes because the database is too large.
That’s why I was asking if you had an older version of your app around, so we can see if verify that this is in fact the case.
I did finally find an older version of the project. I sent you the OneDrive link to it. Hope it helps.
As I mentioned in another mail, this SQLite utility has been in-use on at-least 3 versions of the iPhone and 2 or 3 versions of NSBasic. There has never been a problem on the iOS device dealing with this sized database.
