No longer working ? – Disney Stickers: Mickey Review

My Disney Stickers for Mickey, Princess and Beauty and the Beast no longer show up. I noticed this a few months ago but nothing has changed even with iPhone 8 Plus always up to date. What is wrong? I spent money on these, would love if they worked, not sure if I’m the only one experiencing this problem. Otherwise 5 stars when I had them!
