      Hi, I  have a few months with an LG OLED C3  and tis week started to turn on different.
      I'm aware that the Web OS logo appear when the TV install an update but that logo has a power outlet underneath and everytime I turn on the TV it's just the Web OS logo and my homepage takes like two seconds to load the order of my apps.
      Is this normal? English is not my first language so sorry if it's hard to understand.

      webOS updated, I think to 2023, on my C2 a couple of days ago. Since then the News option on the Sky News app no longer works, instead timing out. The Weather and Climate options still work, though.
      I have deleted and reloaded the Sky News app, but the problem remains.
      Does anybody have any suggestions of what I might try to get this working again, or is this something for LG, or Sky, to fix?

      After viewing photos/videos on a flashdrive plugged into the USB of an LG TV and using SmartShare to view... and then removing the USB and then no longer having access to the TV... I noticed on the flashdrive a new folder called "LG TV" and within what appears to be files that may have been the thumbnails displayed on the TV. My question is... do those thumbnails also remain on the TV as recent history even without the USB plugged in? The LG Smart TV online user guide refers to "Recent" ("To view a list of recently viewed or added content, select Recent). Would thumbnails be there without the source flashdrive?

      We have two LG TV's that stopped connecting to our PLEX media server after the last update. TImes out saying "Checking connection speed to Raspberrypi" which the PLEX is on
      Upgraded the Mesh Routers before trying anything, still only the PLEX app doesn't work
      Our other TCL TV and Roku and TIVO still work with Plex, so this is only the LG TV's that can't connect anymore.
      Another annoying error after the last update is that any Streaming app (Amazon, Netflix, and DIsney) now fall out of the app and go back to HDMI port 1 if we pause for 30 seconds.  Which we have always done for a Bathroom break or getting drinks.

      Hi I recently updated the software to 5.30 version, and after that I noticed a weird problem with video streaming, in general issue with internet bandwidth. Usually my b/w is ~35 mbps so that is sufficient for 4k streaming on youtube or netflix. The issue is after running for 10-15 mins if I pause the video or go backward the network speed is thrashing badly. For example when I check internet connection on netflix it shows ~30-35 mbps, but whne that problem occurs and I check the speed again I see the speed is dropped to <1mbps. Same with youtube, it can't load 4k videos anymore as the speed is ~1mbps. I can realize the problem as the thumbnails load very slow with scrolling. This problem does not get away unless I restart the TV or disconnect from wifi AP and connect back. The router always works fine I mean when I observe the problem on tv I can run videos on mobile seamlessly and see a speed of ~40 mbps on the same router. The router is kept next to the TV so I don't think it is some issue with wifi distance etc. I don't know what to do. I tried resetting but it removed all my app but it was actually not a so called "factory reset". So software version remained same. To rule out hardware problem I want to revert to previous version of the software but apparently I can't downgrade the software. Is there any other approach to load some previous version firmware?
