I saw that by default the plugin for Firebase upload was only accepting image files. I edited the plugin following some answer from @Antti_Neonto in another post asking about accepting mp3 files, but I wrote specifically pdf and now it is allowing me to upload them in the computer.
The issue is that I can’t in the mobile. I have tried in my iPhone, no idea if it would work on Android, but I can’t select any kind of file: nor pdf or any other. They all appear grey and not selectable.
Any way to fix it?
