I am experiencing this in my bedrock Realm on the easternmost gateway. Playing 1.20.62 and killed the dragon, was able to go through the gateway one time, but then now whenever we go through the portal, it loops us back to a few blocks to the north of the end portal. First time going through it worked, but successive attempts put us back on the main island. I flew out to the gateway in the outer end and there are now 4 end portals stacked on top of each other on the exact same coordinates.
I am consistently also having this issue for playersSleepingPercentage and it is really annoying to have to reset it every day. It makes me want to go back to using a mod for it, but then it considers it "cheating" and you can't get advancements.
We continue to see this with a friend who has a slower connection. In one instance, my son and I were playing on our PCs and our friend was coming from the nether to OW and we could see him in the portal, suffocating, while he was still seeing the building terrain screen. He died and dropped everything where we were, and some items ended up in the nether while others were in the OW.
This is definitely preventing him from playing on our Realm with us currently, or when he does play he is forced to stay in the OW dimension for fear he will lose all of his gear by dying in a portal again.
Even with my much faster internet connection, it is still common for me to lose a heart while traveling between dimensions.
My daughter plays exclusively on an iPad and has been having trouble with this. She also tried to customize the location in the latest version (1.20.71) and it simply will not save the controls location for her. She has smaller hands, so the new location of the updated touch controls is simply incredibly annoying for her. She refused to even platy yesterday when she encountered these issues, and if it is not resolved will likely just stop playing altogether.
