[pve-devel] [PATCH pve_flutter_frontend v2 1/1] fix: android: add network config to support custom certificates

[Shan Shaji]

Apps targeting Android 6 (API level 23) and lower trust the user added
CA store by default. However, apps targeting > API level 23 need to
explicity mention trust anchor in the security configuration [0] to
trust user installed certificates.
