I have an s21 plus and the issue I'm having is that when I get sent pictures, it comes up as automatically expired.. like it expires the minute it's sent and when I click it, it says somethings wrong. Here's the catch though, for some reason it doesn't work when my sister, (Galaxy, verizon, diff plan) sends me pictures or my husband (Galaxy, Verizon, diff plan). However, my mother, who has an apple, with Verizon and shares the same plan with my sister--- her pictures send. Could someone help me with this? Samsung just told me to get a new phone. Thanks
