Zac Hall, 9to5Mac:

Earlier this year we reported issues with using the LG UltraFine 5K Display with new MacBook Pros near wireless access points including Apple wireless routers. LG acknowledged issues caused by poor shielding, inventory was pulled from Apple Stores, and revised hardware with proper shielding is now shipping and should be in Apple Stores soon. This week we got our hands on one of the new models with shielding improvements to put to the test and see if the issues have really been resolved.

A rare third party product that has become critical path for Apple. An important problem to fix.
