Cannot join world - Can’t play with kids on two tablets

Hello, I am getting an issue “Cannot join world. The account you are signed in to is currently playing in this world on a different device.” As a result we cant play with kids together in a LAN game. With the new world it works, but as soon as we close the game a join again, only the first player joining the world can play it. Each tablet is with different Apple ID, Minecraft accounts are also different. This issue has been persisting for already several months and I could not find any solutions so I am logging it here. Hope you can resolve soon before my kids get older and will not want to play with me… 😞
