Symptoms

User-visible

  • Some iOS users who sign in by email and password received login links that did not complete authentication.[1]
  • Orders using legacy split payments with a native payment integration closed without a payment confirmation, only on app version 26.22.[2]
  • Photos from the camera roll did not display in the creative tools of iOS app version 10.50.0.[3]
  • Some users saw the authenticator app crash on open after the latest iOS release.[4]

Monitoring-visible

  • The engineering team identified the camera roll fault by reviewing incoming user reports.[3]
  • Customers contacted support about camera roll photos missing in iOS app version 10.50.0.[3]

Root causes

  1. stage: code A race condition in app version 26.22 caused legacy split payment transactions to close without payment confirmation.[2]
  2. stage: release-process Each fixed build had to pass store review before release, so the broken version stayed live while the fix waited for approval.[4][1][5][3]
  3. stage: release-process Recovery depended on each user updating to the fixed version once it appeared in the store.[4][1][2]

In report [1], an iOS release stopped email login links from completing sign-in for some users. The team stopped the rollout of the affected version. A hotfix was submitted for store review. The corrected version became available about two days after the first report. Users were asked to update once the corrected version was in the store.

In report [2], the split payment fault came from a race condition in app version 26.22. The team waited for the updated version to become available in the store. A workaround of enabling advanced bill splitting was offered in the meantime. Hotfix 26.22.1 shipped the next day, and recovery required users to update.

Questions

What causes app store rollback not possible?

A defect ships in a store release, and each fix must pass store review before users can install it [1]. In one report the defect was a race condition in app version 26.22 [2].

What are the symptoms of app store rollback not possible?

Five reports describe a broken flow that stayed live while a fix waited for review. The broken flows were login links, split payments, camera roll photos, app launch and inspection forms [1] [2] [3] [4] [5].

Which test class catches app store rollback not possible, and what does it miss?

End-to-end tests and canary checks are listed, both with the by-design label. A halted phased rollout does not help users who already updated to the broken version.

How long did it take to detect app store rollback not possible in the public reports?

None of the five reports states a time to detect in minutes. In one report, the corrected version was available about two days after the first report [1].

What should be checked before a release to prevent app store rollback not possible?

PR-04 runs a legacy split payment order and confirms the order closes only after payment confirmation. PR-06 confirms before submission that the release is set to phased rollout and that the named owner can halt it.

Should a team roll back or fix forward when app store rollback not possible happens?

Rollback is not available, so all five reports fixed forward through store review. FM-02 halts the phased rollout and FM-04 publishes a workaround while the fix waits. In one report, recovery from the crash on open came only as users upgraded to fixed version 26.2.2 [4].
