It's not clear to me, when I upload a new beta and it's approved for beta testing, and I expire the older build, does the older build stop working for users who are currently testing it?
When I expire a build does it stop working immediately?
Old post, but I don't see a clear or correct answer posted, or the behavior may have changed since this was posted so putting this out there...
Manually expiring a build in TestFlight only prevents a user from installing an older build. See:
Key phrase:
"Internal testers and external testers will no longer be able to install this build."
Says nothing about preventing a build from running, just that they can't install it. Working with TestFlight on my own devices and apps, I've had very old builds that I "expired" that continue to work.
Make sure you communicate to your testers that they need to update the app every time they receive a "new build available" notification.
Apple Support confirmed that an expired build will cease to work period. This also means that developers can no longer access the build for debugging purpose, such as a crash reported on the build.
@jeancachu, that has not been my experience. I have a TestFlight build that has been expired, yet it can still be run.
