XR15 Remote stopped controlling LG TV and LG soundbar at the same time

I have an LG TV and LG Soundbar. I am using an XR15 remote. For years I have been able to control both my TV and my soundbar simultaneously with the XR15 remote until last week it just stopped being able to pair and control both the TV and the soundbar at the same time. I am able to pair the remote to the TV and it works but as soon as I pair the soundbar, the remote stops working for my TV and vice versa, if I pair the soundbar first it works with soundbar until I pair the TV and then only the TV works but not the soundbar.  I have done a reset of the remote as well as trying a different XR15 remote from another room butbthat did not fix the issue. I have tried each code that xfinity supplies for both the LG TV and LG soundbar but I am still not able to control both devices at the same time. I contacted customer support but all they said it is a known issue and would be fixed in 12hrs but that was 7 days ago and still not fixed.

How can I get my remote to control both the TV and soundbar at that same time like it always did?
