We use enterprise in-house distribution to distribute the Alpha builds of our mobile app to internal QA teams and to company employees that volunteered to test the builds. These are app instances that point to system integration test environment (SIT) or QA environment. Only devices that under MDM can connect to QA or devices in a private company network can do so.
with the custom apps now becoming the default distribution mechanism and enterprise becoming possible for cases that cannot be covered by custom apps per wwdc 2019 video on business apps,
1. can we continue using enterprise in-house distribution for the above case?
2. If we should move to testflight, we will need to distribute to external group as the 25 internal will not be enough for our test group. in that case would apple review allow us to distribute apps that link to internal environments for testing. In this case of course the final release candidate build will test against production and that's the one that will be released to production.
Thanks!
