I have a new LG Frame TV (2020) and I have configured everything to work via the LG Smart Remote. I have configured the TV to know that the V6 box is a DCX960 and everything works fine. However some times I do see an audio sync issue with some channels (that seems to go away when using pass through in audio settings on the TV). However the biggest issue is that after the box goes to sleep over night then the V6 remote can no longer control even when it's turned back on. Even if I switch the box off and on again it still doesn't work and I have to use the V6 remote to control it.
Are you using Eco Low Power or Connected on Low Power settings on the V6? If so change it to Always On. This will help the V6 as updates are always performed overnight and will also help with populating the TV guide.
