I only use Inventor every few years, and Androids seem to change every time I try to use them.
I'm trying to read a text file with the FILE gadget, and for the life of me, I haven't been able to specify a path that works.
If I connect my phone to my desktop, Windows Explorer shows my file in
"This PC\Galaxy S21 5G\Internal storage\AppInventor"
I've tried a dozen different paths and the all cause "can't find file" errors.
For example, I've tried
/AppInventor/test.txt
/storage/emulated/0/AppInventor/test.txt
/Internal Storage/AppInventor/test.txt
A ten minute quickie has already consumed a couple of hours!
