Online Co-Op PC and PS4

Hi there

I play POE on a windows PC and my friend play on a PS4.

We can not see each other in game nor can we message or invite into a party etc.

We have in the same league and on the same server.

Anyone tested this any might have a solution to how we could party up and play together?

There's no way for cross platform co-op.
