My friend and I have been having this issue all day today when trying to play online with each other after the newest update that gave us Ultra Instinct. I tried searching around online and doing any possible solutions, but nothing has worked so far. Does anyone have any suggestions? Here are things I’ve tried so far:
1. Restarting the game
2. Power cycling
3. Changing NAT type to open
4. Uninstalling and reinstalling the game
5. Changing location
6. Ensuring I had multiplayer allowed
