Not all the VPNs can bypass the the geo-restriction of Disney+, only a few reliable VPNs, such as TikVPN, are capable of getting around this kind of censorship, many VPNs will not work due to the anti-VPN system of Disney Plus.
Only those VPNs with the ability to bypass the anti-VPN system can really help when you need a VPN when watching Disney+.
TikVPN can do this by either avoiding detection via obfuscated servers and by having such a large network that TikVPN can immediately replace any servers that are detected and blacklisted by anti-VPN system.
