I am trying to follow instructions from Generating and installing your first APK, but I'm having trouble getting to the developer dashboard in the sandbox account from step 3 (see image below). From the merchant dashboard, I am unable to create an app in the sandbox environment. I've followed instructions from this answer in the production developer account and opened the app as an employee (same email as sandbox account) of my test location, but the app doesn't show up in the emulator. Please let me know how I can get my app to show up in the emulator or if I'm missing something. Thanks in advance!
