My app wont i stall it will only open

I'm sorry. But I don't understand what your saying . Can you come back and clarify please?

It sounds like your app won't install it will only open..Makes no sense. If it will open, then it's already installed.

If your eBay app opens, that means it is already installed.

If your app will not open, try uninstalling the eBay app, restarting your device, then installing the latest version of the eBay app again.
