Mage Portal spell not working ?

Hello, I play a mage currently level 40 and I learned the portal spell. The spell works, I see the portal open and I can use it but the players in my group can't use it.. It should be pretty easy to use.. Am I missing something here or is it broken ?

The other problem I have not related to the portal spell is the Enchanting prof. To my knowledge it's possible to enchant soulbound items of another player through trade but every time I tried, the trade just closes when the enchantment is finish. Leaving me with all the mats used and the item in question not enchanted.

I've looked on the forums but didn't find anything related to my problems.
If anyone can help, it would be appreciated. Thanks !

If you enter the portal first it will not allow your party to use that portal.
Make sure you are the last person through it.

As for Enchanting through trade that is a bug, and I think it already has been reported.

I'll test the portal spell again, I believe the player in question tried before me but we'll see. I will edit this post after the test.
Thanks for the reply
