From about 12noon on Wednesday - the day after the overhead problems at Deansgate- Castlefield, the Trafford Centre trams were curtailed at Cornbrook:
"Due to an inspection of the overhead line. Trafford Centre - Deansgate services are currently operating Trafford Centre - Cornbrook".

This continues as at 1000 on Friday.
Seems the errant tram 3132 was working a Trafford Centre tram from the middle track at Deansgate-Castlefield and had a problem whilst traversing the points to the main southbound track
The network between D-C and Cornbrook usually has 8 trams every 12 mins each way during M-S daytime - hence the number of lines affected on Tuesday (Two to Altrincham, two to East Didsbury, plus one each to Airport, Eccles, Trafford Centre, Media City)
On Tuesday, trams from Altrincham were curtailed at Old Trafford then entered Trafford depot to emerge back running to Altrincham. Similarly East Didsbury and Airport trams did the same to emerge back to the outer destinations - so the depot roads must have been busy with trams terminating.
It seems this congestion wrecked the frequencies on the affected lines with gaps of upto 20 mins on the Altrincham line with PIDs at Sale showing three lines of "DELAY" heading for Altrincham around 2.15pm, and PIDs into town showing "Old Trafford" but also "Bury" and "Piccadilly" at times when all trams terminated at Old Trafford. Seems it is difficult to keep the PIDs upto date at times of disruption.
The Bee Network APP regularly shows different times to those shown on the platform PIDS - presume the information comes from different systems??
