I bought both Ruby and Sapphire for my girlfriend and myself to play.
After getting some medals and catching some Pokemon we decided to trade and battle a bit with Pokemon level 20 and having only 3 medals.
We appeared in the PSS as friends online and we can issue battle or trades, but after accepting a message displays and the attempt is canceled. The message we get is:
Combat/trade canceled any of the participants is missing
- We tried to trade and battle people online and we don't have any problems.
- We used local trading/combat. Tried internet too
- The Pokemon where caught and raised in-game, no hacks nor strange trades with other games.
- I have a 3ds XL and she has a new 3ds XL
- Both games are updated with the latest patch
