I do not know if it is an error or to put it as a suggestion but I come to talk about an error in the portals to the nether in minecraft bedrock edition is that many portals are linked to only one and it is always very annoying that you play on a server they authorize the nether you make a portal and you make a base around the portal and all the players appear there and if you go to the normal world you appear in any portal
