I encoured an issue about using Youtube inbox integration. When adding a link (eg. Clown takes the robocar Poli toys' salute. - YouTube), it display video in post edition preview, but when saving, subject is empty, and there is no possibility to edit it.
It was working few time ago. My current discourse version is v1.6.0.beta1 +281. Someone else detected this issue?
Thank you for helping me!
