Describe the bug

It looks like the latest update has altered the file/folder process and it isn't seeing MKV files. I tried it with a USB with only an MKV and it didn't show it, saying no media files. I've gotten mp4 and others to play properly. I also checked the file permissions in settings and it was the same as before.

Expected behavior

The previous version had all the folders instantly and was able to play/show all file types.

Device (please complete the following information):

Android TV (Sony)
