Regarding Custom App

I want to create a custom app an install it on my wix development site but when doing this every thing is going right & I’m able to create access token using advanced oauth flow.
But in the end install count of my app is showing 0, on the other hand when opening wix dev store it is showing app is installed.
Another problem is that when using the respective access token i’m getting that app is not installed on respective store.

Anyone please help
Thanks in Advance.
