I cannot see portals in a party or teleport to party members locations !!!

I do low level waystone maps T 1-5 and now if i enter a party i cannot see portals or teleport my party members locations .
is there a fix to this bug ? is it a bug ?

When you join as a new member, while they are in an instance you can't see their portals. Host needs to leave the instance for you to see them. A workaround is for you to join the host hideout and start maps from there and you will see the portals every time. It's a bug for sure.
