Your latest version

As you release version 5.0 , it’s not work again as before, crash as tap to open.

Developer Response ,

Edit: The current app version is now 5.0.5. If you re-install the app to the current release can you see if that fixes it? Or are you saying it also crashes after you re-installed it with the latest version?

Also, you should verify that you are running the most recent version of iOS (13.4.1).

Edit: a possible solution seems to be to delete the app then install it again. It could be an iOS caching problem.


Sorry to hear you’re having issues with the app.

Is it possible you can send an email to so I can take a look into what’s causing the problem?
