Fortinet 101F (FortiOS 7.0.2)

Hi! I would like to ask why my firewall policy reflects only on my phone and not on my laptop, even though they’re in the same group (Semi-restricted) that I created. I blocked or restricted some websites using their MAC addresses, but the restrictions only apply to my phone.”

What's your topology? Run a sniffer and check the source mac of the incoming traffic and make sure it's the same as blocked mac.

Sniffer:

dia sniffer pack any "host x.x.x.x" 6 0 a

If you have L3 switch between your laptop and FGT, then source mac will be mac address of the switch.

Hi! Here's our topology

ISP -- > FORTINET <-- ACCESS POINT --> USER

Until now, I am struggling configuring this firewall, I don't know why the firewall policy only reflects on my phone but not on my laptop even though they're both in the same group

The description of your issue is a little too vague. 

Is the same firewall policy matched by both devices? if not, check the difference between policies.

Check the session list and filter by source IP for both devices Troubleshooting Tip: FortiGate session table information

"I blocked or restricted some websites" > how/which security profie? which websites? which browsers? how is the policy configured flow/proxy?  deep inspection or certificate? 
There are too many variables to consider.
