We are changing the way we handle app defaults on merchant groups. Starting today, merchant groups will be associated with a single app version. If you want to test a new version, you'll need to create a new group, with the desired user base, and associate it with the desired version. This change should give you a bit more customizability, handling various app versions and merchants running that version. When you're done testing, you'll want to remove the existing merchant groups, and submit your production app update so all of your test groups get the updated version. Feel free to reach out to us if you have any questions.
