title: Missing dSYM files in Fabric Crashlytics
body: <p>Since yesterday I try to configure Twitter Crashlytics in my iOS app. 
  I have a problem w dSYMs files. Fabric dashboard show me message "We are missing dSYMs files" so I uploaded the files by online manager (redirect from this message) and this message was shown: 
  <a href="https://i.stack.imgur.com/dVkfw.png" rel="noreferrer"><img src="https://i.stack.imgur.com/dVkfw.png" alt="enter image description here"></a></p>
  
  <p>but if I go back to dashboard the message that system missing dSYMS files is shown again.. and again. 
  What I have to do? </p>
