I hope this is the right section to post this problem. I downloaded an MKV file using Terra Browser. When I go into "saved file" and I tap on the mkv file, a warning message appears saying that "File has no associated applications on this iPad"..... of course, I do have an application which plays mkv's, which is GoodPlayer.... Since I do not know who manages the file association table (is there an iOS one only or does each app have its own? ) I cannot understand where the problem is. Any clues ? Is this working "as designed" ? PS: I had to change the post since I reported the problem incorrectly initally. sorry about that.
