VPN Updates
According to a YouTube comment:
ExpressVPN allows 14 simaltaneous connections, not 8 as shown on your Techlore VPN page, which you show in this video. Also it specifies ChaCha20 as an option on some VPNs but more than those listed also have that option. Including ExpressVPN.

Server authentication Like HTTPS and OpenVPN, Lightway uses certificates to protect the user against man-in-the-middle attacks. Your VPN client has a certificate preloaded that is used to authenticate a VPN server.When using an external or open-source Lightway client, you will be able to load this certificate yourself to connect with VPN servers.
The two ciphers used in Lightway are AES-256-GCM and ChaCha20/Poly1305. Owing to the excellent hardware acceleration of AES available in most devices, Lightway will mostly default to this well-proven cipher. Only on lower-powered routers or entry-level mobile devices might ChaCha20 be used.
