not sure if you guys realise yet but there are afew things you should know;
- friend trade is local only, you need to be close together
- room trade requires 3 participants minimum
- you cant trade mythicals/ 'special' mons in ANY WAY in home - they are always grayed out - even in a sucessful room trade
if you want to trade meltan, it has to be via SWSH
absolutely ridiculous if you ask me.
