I tried to make a scoreboard shop and it doesn't give me some things that offered on the shop and the command is only able to test my scoreboard money rather than taking it and put some item in my inventory

The chain doesn't seem to work on @p I know scoreboard commands work but they won't now.

But to test it emulate Android 8.1.0 (Go Edition) with specs of MediaTek MT6580 (Arm CORTEX A7 4 Cores 28nm with 1gb ram (obviously gapps eating more ram than Minecraft itself) with Bugged Mali 400MP graphics

Try to use Minecraft on slowest device and execute commands on scoreboard via command block but does not work.
