LG TV with magic remote - won't control Sony Receiver and LG TV

SO I've seen other posts discussing this, but the fixes suggested didn't work for me. Open to input from the community.

Situation: I have a LG TV with the magic remote and audio via an older Sony receiver. X1 with XR15 model remote. Old system (X1 and XR11) worked fine controlling all components. Replacing the system with the newer remote and I have an either or option.

Whichever I pair last can be powered off. I have tried all the Sony and LG remote codes on the remote pairing help for my brands. When I am in the situation where I can power off and control volume on the Sony, I can still use the tv input button so I know the code is saved properly, but the power button only turns off the Sony. When the last code entered is the LG TV, I can power off the TV, but no controls work for the Sony.

Any suggestions beyond what I have tried? I have also done the setup walkthrough which did detect the LG TV and walked me thru Sony receiver setup until I found the first function code. Same issue.
