In a Facebook post by P2P Premium Bus Service, the route from Eton Centris to Glorietta 5 has been suspended.
The reason for the suspension is the lack of passengers going to Eton Centris for the P2P bus service. Instead, they will re-route all the buses, and place them in the Trinoma terminal for the Trinoma to Glorietta 5 route in order to accommodate the heavy influx of passengers using the P2P service there.
It has also been mentioned in the post that they will come up with a solution to revive the Eton Centris to Glorietta 5 route in the near future. The suspension of the P2P service has been in effect since July 31, 2017.
