Hi Alexander,
Just took a quick look our side and we are transiting both paths properly
(best path for TCL for us is still via Telstra in Australia). I suspect
some sort of broken URPF or a stateful device that doesn't like asymmetric
paths will be the cause of your issue and it's likely inside the smilecity
environment.
