[2019] Bug: Draft mode is stuck, any advice?

Hello,

Trying to do some draft and my opponent dc'd turn 1. Now the match is stuck on my opponent's turn and won't progress. Been stuck now on his turn for twenty minutes.

Relogged and rejoined the match 5 times and didn't help.

Is my only option to concede the game or is there something else I can do?

Didn't see any tech support section on the LS website btw so thought this would be the best place to ask.

Thanks in advance.
