title: React Native - sometimes app freezes when opened from background
body: <p>Recently I noticed some strange bug in my IOS app (on Android I did not see that problem so far). </p>
  
  <p>When the release mode is installed on my real device (the same problem happens even with production app from App Store), and when the app is opened from a background where it was for example 1,2 hours - my app freezes for several seconds (I can scroll my lists but Touchables are not working). Sometimes it freezes 5sec, sometimes 10sec... The freeze time is not constant.</p>
  
  <p>For navigation, I use React Native Navigation. First of all, I thought that it can be a navigation problem - but I can navigate through tabs. So I can navigate through tabs, can scroll FlatLists in the tabs, but the list items are not Touchable - I can click them but onPress is not called.
  And after several sec when the freeze is over - my app does all pending navigations. Namely it opens all screens which were tapped while the app was frozen...</p>
  
  <p>Who had such kind of problem? And how can I solve this? Please help, I am stuck here a couple of days :(</p>
  
  <p>React-Native: 0.59.10;
  React: 16.8.3;</p>
  
  <p>Thanks in advance</p>
