Minecraft Realm Lag

Yesterday everything went perfectly fine, today I,m trying to join a realm of a friend and I can't join it, when my friends are already in the realm,the whole entire realm is frozen, they can move but if they break/place/use anything it won't work, if I leave my character is still there for 5 minutes, after it left everything (player,blocks) is reloading and u See everyplayer moving super fast around.

Please try to fix it, I love the realm and we build too much to loose c:
