I have been tryinng to set a date with my opponent. After some effort, it seemed like we had agreed on a time, but he never showed. After that, he never answered any of my messages to find another date and time, even though he has online at least once since then. I have tried sending one last message today, but even if he answers, we are in very different time zones and the window of hour when we can play is reduced.
Similar to the above - while they have apparently come online a couple of times, they didn't reply me or ping me on Showdown (I've been online nearly continuously since 8 October so I would be able to see any pings related to Modern Trio that way, even if I were sleeping)
My mistake for going through with a Gen 8 Random Battle instead of Gen 8 Random Battle (No-Dmax), sorry. We still have one battle left to complete and my opponent hasn't been online since our last match.
