If you are using a registered version, disable the splash and progress loader then try again. Since that is where the crash is happening, remove that first. If the problem persists, try Google's advice here: https://support.google.com/chrome/answe ... ktop&hl=en

You say that the game works on desktop but not on phones since updates. Has the game become so huge that you have run out of memory?

I guess I would probably start working backwards if I were you. Make a copy of your capx and start removing code that was added recently and retest until it works again. Its a pain but might be the best way to debug. If you need a quick way to test on android, there's a 99 cent app on Google Play called 'HTML5 Loader' it might help save some time since it will run the project without compiling to APK and installing.

Unfortunately, digging through the code in the capx is where most would start when trying to find the solution. From what I can tell, the problem might be the ads and shop. If it runs in browser while ignoring ads and shop, that might give you a clue as to whats causing it to crash. Have you tested it in mobile browser yet - without building APK and installing? Doing that might give you a clue as to what is going on. Search Google Play store for 'HTML5 Loader'. There's a 99 cent app that can be used to load and test HTML5 projects without building to APK and installing. Or, put it on a web server and browse to it with your phone.

Another thing you could do is try using an android emulator if you think your android is old: https://developer.android.com/studio/run/emulator.html

Also, make a few copies of the capx and start working backwards (dont want to trash your original project). Remove the code that you think might cause a crash and then re-test. That might help you narrow it down.

And one more thing, try using a different tool to compile your APK. Sometimes the bugs are caused by the compiler and not the coder.

As for IOS, I cant help you at all there. Good luck and try not to give up.
