I had the same issue after updating WebOS. The TV was still visible in Homey, but it stopped responding in Flows.
After removing the TV, I couldn’t pair it again because the PIN code was no longer shown on the TV.
The developer confirmed this was caused by the recent update. I installed test version 1.0.6, and that fixed the issue. The PIN code is shown again and the TV can be paired normally.
LG says an official 1.0.6 release with this fix should be available soon.
