Why doesn't Samsumg fix the subtitle bug with firmware 1401?

[oliv2000]

I have the Samsumg model Ru7475. In august 2022, firmware 1401 was updated, spoiling the subtitles with external files. It seems to be happening in more 2019 tv models. why hasn´t Samsumg fixed it after 7 months? It seems that Samsumg makes planned obsolescence with its TVs. I amclear that it is the lsat Samsumg product that i have

Hello I have a similar TV UE43RU7410UXZT and I face problems with the 1401 update.

When I play any MKV file with subtitles are not displayed immediately, I must go back some seconds with the left key. And then the last subtitle remain on screen indefinitely until the next sentence. Very annoying.

With the previous firmware it didn't happen.
