I have a max level beacon (Lv. 4) and it's placed at 3959, 63, -602 but wouldn't give effects at 3909, 70, -552 but even if I got closer let's say 3913, 70, -557 I still don't get effects and next to those blocks is a auto redstone contraption for wool and going near it stops the beacon from giving effects. The world the beacon is in is a realm world if that helps. Screenshot_20210329-180032.png is the back of the contraption that shows most of what redstone items where used. In Screenshot_20210329-180412.png the floating blocks around the contraption is where the effect doesn't give off to the player and the purpur Block is located at 3908, 70, -552. I own a PS4 and it still happened on that platform too.
