WE ALL HAVE THE SAME VERSION(1.21.44)

So me and my 2 classmates want to join the worlds i have downloaded on my phone(android 11) using one of my classmate's phone to host. After that it didnt work and the freinds tab only shows 0 and didnt show the world. I tried using one of my classmate's phone to host(android 12) and the LAN world didnt show up. However, one of my classmate want to host a hardcore world using his phone(Iphone) and were shocked to see his LAN world appearing on our freinds tab without internet. We were only just connected to another phone's hotspot without mobile data/no internet.

PLS FIX THIS IDK WHY IPHONE CAN HOST OFFLINE LAN AND WE ANDROID CANNOT

(I have turned on the "Multiplayer world" and "Visible to LAN" on the world's setttings and still didn't work)
