[2021] Can't enter the Capitol Building in WT5. Prerequisites not met

I'm sorry to hear you are continuing to have this issue with reactivating the SHD Network, nikon123. This issue is something our team is definitely working to resolve. If possible please see if you can play through the mission on story mode in matchmaking. To the best of my knowledge this will resolve your issue if you stay in party until the other player has reactivated their own SHD network. I understand that this isn't a fix, and I can assure you that our team is working to resolve this issue. It has been a tricky one to fix from what I understand.
