We already have web app exist on Square app marketplace.
Now, we’re developing a new Android app.
Is there any change in the app approval process?
How long usually it takes for a new app to be approved?
You’ll want to reach out to your contact with the Partnerships team with those questions. As far as I know there isn’t any change to the approval process. If anything were trying to make it faster. 
Hey Bryan, we’re trying to reach our previous partnerships team but no respond.
Is there any specific email we can reach for the partnership?
Thanks
No there isn’t any other email other than the one you probably already have. When did you reach out?
