Hello Mojang,
Since my phone updated from Android 9 to 10, and Minecraft update the 11 june, i lost all my friends. Moreover, my micosoft acount disconnect himself. My minecraft name changed from "Eina011" to "Eina0119926" while my Xbox account is still "Eina011#9926". Tsunaka#2994 encountered the same issue, but without losing his friends.
Could you watch about this issue ?
Cordially,
Eina011#9926
