Try using Pocket Code 1.2.4 and tell me if it works. I did some tests but they didn't work because I used a copy version and I can't uninstall Pocket Code because I would lose all my progress. So try it yourself and tell me if it worked.
On 1.2.4 how to import the file. When I import it it takes me to image editing
you can see here
Ok i'll try again
I can't open the file. It says an error occurred in a program.
Nooo
Too bad
