I have successfully imported audio tracks from a variety of sites. However, after a few uses, say after a day or so, they stop working. When I check the same tracks in my Music folder, they all play normally in Windows. Other audio files from roll20 supported sources, such as Battlebards etc. work fine. Has anybody else experienced this & is there a solution? I like having music and sound effects in my games & this is really killing the roll20 experience for me. Thanks in advance for any advice!
