POE2 Party Trading Connection Issue!!!

Hi there is an issue with the connection of instances. Many times you can invite a person to party that wants an item they join the party but they dont show up on screen as in party sometimes it works if you message them and get them to invite you to party and then they appear and can travel to you to buy the item but so many times people just move on and it looks really bad. Even had nasty messages sent as if its my fault. It doesnt happen all the time maybe every 3rd sale sometimes when im mapping sometimes when sitting in hideout. Pls fix. Theres obviously some issue with connection between instances.
