Multiple game instance not working.

I believe that Multiple game instance is not working with the new update that occured on roblox yestarday. I have tried opening 2 intances to no avail and after some testing it seems that you will run into the unexpected client error if you do try to open a second one, forcing you to close the second one. Please let me know if multiple game instance is working for you and if you find a work around please post it down below.
