I know that free unencrypted-Wi-Fi is dangerous since all the traffic in the same AP is visible.
Does Wireshark capture all Wi-Fi traffic under the same access point even with WPA encryption?

To decrypt WPA-encrypted Wi-Fi traffic in Wireshark, you can follow these steps:
Capture the Wi-Fi packets using a capture tool, such as Wireshark, on a device connected to the same Wi-Fi network.
Export the captured packets to a PCAP file.
Open Wireshark on a computer and go to Edit -> Preferences.
In the Preferences window, select "Protocols" and then "IEEE 802.11."
In the IEEE 802.11 preferences, click on "Edit" next to the "Decryption keys" field.
Add a new decryption key by clicking on the "+" icon.
Enter the SSID (network name) of the Wi-Fi network, choose the encryption type (e.g., WPA or WPA2), and enter the encryption key used by the access point.
Click "OK" to save the decryption key.
Open the captured PCAP file in Wireshark.
