Can confirm on Android as well

Relates to MCPE-25228

@bugsbugsbugs This is actually novel to the 1.15 & 1.16 betas.
(Unless you mean it's related in that the same code is what's wrong with it).

This is duplicated by MCPE-69442 (1.15 RTX) & MCPE-76708.

@Douglas F Correa I just meant that it could be related to it, because it is a simelar issue, where the beacon beam disappears when being far away from it. (The distance where you can see it is too low on bedrock Edition.)

Confirmed for Xbox One
