I can't get ShareFile to work. I've used SaveFile to save a (txt or csv) file (e.g. \filename1) which I can retrieve using ReadFrom, but ShareFile doesn't work. Whatever file path I try (including the suggestions at http://ai2.appinventor.mit.edu/reference/components/social.html#Sharing) it produces an error message saying the file could not be found. I've tried it with LegacyMode turned on and off.)
I originally posed this question in August 2019 with a suggestion that the way the Sharing component treats file paths should be consistent with the File component. I received an acknowledgment from Susan Lane, but heard nothing more. At the time I abandoned the Sharing component because I could easily use other apps (mainly Google Drive) to share my files. However, I now learn that this will cease to be possible as Google are not allowing apps to use shared space in storage (http://appinventor.mit.edu/blogs/evan/2020/08/08/file-path-updates-android-10#what-this-means-for-app-inventor-applications). This means that using the sharing component is now essential!
Many thanks in anticipation of help.
