Just some extra info on this I posted a ticket in support and the response was:

Unfortunately, we do not have any ETA on when a potential fix will be implemented, but please keep an eye on upcoming patch notes for more information. As for the reason you did not receive a response on the bug report you submitted, these do not receive responses in-game, but let the correct team know about the issue that's taking place, so they can investigate further.
