title: Apple Pay Payment certificate is not trusted
body: <p>I am working on implementing Apple Pay in my ios app, For that I tried to create certificates on the apple account.</p>
  
  <p>I followed this <a href="https://developer.apple.com/documentation/passkit/apple_pay/setting_up_apple_pay_requirements" rel="noreferrer">setting_up_apple_pay_requirements</a> link.</p>
  
  <p>and followed the exectly these three steps</p>
  
  <p>1.) Create a merchant ID.</p>
  
  <p>2.)Create a Payment Processing certificate.</p>
  
  <p>3.) Enable Apple Pay in Xcode.</p>
  
  <p>But in my key chain when i added the created certificate, then it is showing <strong>"Apple Pay Payment Processing:"merchent id" certificate is not trusted"</strong></p>
  
  <p>Thanks in advance</p>
