Smart ones Sliced Turkey and mashed potatoes

I used to love the smart ones Turkey and mashed potatoes. Over the last year or so the mashed potatoes are runny and with bits of dried potatoes or something. They used to look and taste like mashed potatoes. I thought initially I was not cooking them properly I cooked a few extra minutes and still no improvement in the potatoes. And FYI I’ve tried buying at various times over the past 2 years so it can’t be a bad batch. Will never buy again
