I have been using the media browser app (1.1.3) for awhile now both by itself and streaming to my TV via Chromecast. I haven't had any problems with playback on my iPad air itself, but recently I have been having many issues with streaming to Chromecast.
Typically, I would have Chromecast started and waiting, open the app, connect to Chromecast, hit the refresh button on the app which changes the TV to media browser, and select content to play. This has, in the past few weeks, worked flawlessly. In the past week or so, the content will play for a few minutes and stop, or not play at all. I then proceed to disconnect, restart Chromecast, restart my iPad, restart the app, restart the server, and even restart my wifi in my attempt to fix the problem. It then might work for one episode of a show, but then not work for the next episode.
Last night a stream to Chromecast froze as I described above, but instead of trying to troubleshoot it I just tried playing back on the app itself without even restarting anything. It worked flawlessly, leading me to believe the issue is not with the server, or my network, but with the app streaming to Chromecast.
Please let me know how I can help resolve what I believe is a bug. If you tell me how, I can send whatever logs the server generates, or I can post a video of the issue so you can see exactly what my workflow is.
