Albion saw controversy strike as they were awarded a penalty, only for the referee to reverse his decision after consulting the pitchside monitor.
On top of that, United were awarded a penalty after Darnell Furlong's unfortunate handball, only to see the terrific Sam Johnstone save Bruno Fernandes' effort.
The spot kick was then retaken after Johnstone left his line early, in which Fernandes made no mistake.
Albion rallied, but could find no equaliser, meaning their search for a first Premier League win continues.
