I've been having this issue for a very very long time since commands are now in the bedrock/pocket edition

Yes, the command feedback was disabled, they no longer pop up when player does the command, but command blocks still shows the feedbacks to the player's chat screen after the command

It's annoying especially when you tried to make command block map

Basically the only command feedbacks that are disabled are from those activated by player chat not those commands activated by command blocks

Executing player in command still shows command feedbacks too

My device probably don't support the command, so yeah, I hate this
