GitHub mitigated the disruption by disabling the feature flag and says it is improving detection and guardrails. The iOS app was unaffected.

## Source excerpt

Between June 19th, 2025 11:35 UTC and June 20th, 2025 11:20 UTC the GitHub Mobile Android application was unable to login new users. The iOS app was unaffected. This was due to a new GitHub App feature being tested internally, which was inadvertently enforced for all GitHub-owned applications, including GitHub Mobile. A mismatch in client and server expectations due to this feature caused logins to fail. We mitigated the incident by disabling the feature flag controlling the feature. We are working to improve our time to detection and put in place stronger guardrails that reduce impact from internal testing on applications used by all customers.
