My app works fine in Thunkable Live both in iOS and Android. When I download the apk and then I install it, the app crashes. I have not been able to test it on iOS because I can not publish it yet on Apple Store. Does someone has the same problem? ---

Hard to say without actually seeing your app, but here are some common causes of crashes: Do you have an active internet connection? Are there any errors in your blocks? Are there any duplicate/conflicting event handlers in your blocks? Does your version number, in your app settings, say `NaN` instead of being a number. ---

The problem waas solved by itself. I do not know what happened but after 5 times of building the app I was able to start it without any crash. ---
