Mech Arena My end or their end?

Also another issue. My only in game sound was 3,2,1, go and music. No weapons noise, neither mine, nor my opponents weapons.

I think it's a symptom of lag...we've been enjoying a relatively lag free game thus far, but I'm starting to see some lag symptoms. For example, War Robots had teleporting bots, but MA has mechs that suddenly slide and move weirdly fast, like one of those stop motion chess pieces and take no damage while moving, but the damage is shown after the mech stops moving. The long wait time could be the game realising that there's no human players but has some sort of delay generating the AI bots for the match. Or, it could be delay in synching up the human players.
