Hello everyone!
If I understand correctly, Android >= 2.3.6 should still work thanks to cross-sign? But my Flutter app cannot connect on Android versions prior 7.1.1 since Sep. 30. Says that certificate has expired.
Lots of messages there, but still unclear what can be done on the server to continue support old (but newer than 2.3.6) Android clients. I'm running an Ubuntu server with certbot. I already told users to update Android, but this option is not always available. It should be possible to solve this issue server-side.
