After upgrading Chromecast with Google TV to version A12 I noticed that, probably due to scoped storage, I cannot write on internal storage. What I'm trying to achieve is transfer some fonts files so that MX Player can read them afterwards. Anyone knows how to bypass the aforementioned problem? Thanks in advance!
Go to settings -> apps -> search for the app -> go to permissions -> and check what options are available, if you see three options, select the one that let you access the storage all the time, if you only see two, select the one that access the storage when using the app, if that one doesn't work, then you're out of luck and you'll need to wait for the developer to fix the issue.
What are you using to transfer the files?
