Since the last Shield update MrMc became rather unstable for me, mostly dropping frames especially if I resume playback, and after uninstall reinstall it won't update the the Plex add on library like it did before. I would still find the files, but won't show under "most recent". Tried different skins as that makes a difference as how content is displayed, but no luck there. Never had issues before the last Shield update. Went to the MrMc forum but I haven't seen the same exact issue mentioned, though there were several similar ones.
