I play on bedrock edition. My Realm was working fine until recently when I downloaded to the same account on laptop. Then the realm wouldn't work on my original device. I deleted Minecraft on the laptop because I thought it would make it work og device. It didn't work and now for 3 days it has just had the same screen. Idk how to fix this or what to do if anyone knows what to do please help.
