Step 1 - Make sure all your products and collections are marked available for Mobile App Creator Sales Channel. (Otherwise, you will see an error page on the app & checkout will not work.)
Step 2 - Complete store listing.
Store listing is the app's information we show on the app store & play store. Here are the steps -
Go to PlobalApps dashboard
Find the "Rocket" sign on the left panel.
Select Store Listing & SAVE.
Step 3 - Share Google developer's access. Help doc.
If you have not created the developer accounts then please visit our help center help.plobalapps.com to find help articles.
Once all these steps are done, please email us at firstname.lastname@example.org & we will upload the apps.
