Without warning or changes to network configuration iPads were unable to connect to friends in games.  We were able to do this on prior days.  We play on LAN only and do not login to any system.

One of the iPads was running iOS 15.xx, so we thought that might be the issue and did an update, but it did not fix the issue.  We uninstalled the game and reinstalled on one of the iPads but no fix there either.  All of our games are on the other ipad that we have resisted deleting the game from and reinstalling (we have over 200 worlds).  Please help.
