I also have issues with subtitles on both my smart tvs.
On the LG UK6950 all PGS subtitles are missing unless I switch to “Always burn-in” both for -
- Some older movie with two audio tracks (English and my native) and a single subtitles track which I know have worked before
- A newely added blu-ray with two audio tracks (English and native) and with two subtitles tracks (native - forced and native).
On the Samsung QN90A the old movie’s PGS subtitles are shown, but the new one are not shown unless I switch to “Always burn-in”, without “Always burn-in” sometimes right after a forced line would have been shown I might see a line of the selected subtitle track
Both my android phone and the Windows app shows the selected subtitles for both without issues
