Hi all - have an UM7500PTA TV and steaming movies from my Synology NAS's DLNA server. (mkv HDR 2160p movies mostly)
SRT embedded subtitles had not been a problem and could select any of the SRT subtitle tracks, but not since 5.00.15 update.
I found a workaround though: if I add a dummy external srt file with one single subtitle inside, I can select internal subtitles and then the "track" button will be active to select any embedded srt sub.
Was looking into firmware downgrade via LgDTVUpDater, but not sure if a 2019 model TV can be downgraded that way.
Any ideas - thank you.
