Glitches especially in parties

Ever since season 2 dropped the loading screens have been incredibly slow. I timed one return to market that took 1minute 30 secs to get back. 
the loading is even worse when you factor in other players or try to enter parties. What’s more annoying is you created the own the lot challenges to do with other people, but most of the time crashes out or just won’t load at all. Every day for the last week or so I’ve had to close the application and start again 2 or 3 times because the game has crashed after completing a challenge
