Recently returned to China from the US — Muse stopped working even with a US VPN. Any suggestions?

I recently moved back to China after being in the US, and Muse is no longer working for me.

I’m connecting through a VPN with a US node selected, but I still can’t use Muse normally. It may be related to region/account checks, browser cookies, DNS leaks, or the VPN IP being flagged.

Here’s what I’ve tried so far:

• Connected to a US VPN server before opening Muse
• Confirmed the VPN is active
• Tried reopening the app/website
• Still getting blocked or unable to use it normally

A few questions:

1. Does Muse only check the IP address, or does it also use Meta account region, app store country, payment method, device location, or browser cookies?
2. Would clearing Muse/site cookies and cache help after switching VPN nodes?
3. Are certain types of US IPs more reliable than others, such as residential IPs versus datacenter IPs?
4. Is there anything else I should check, such as DNS/WebRTC leaks, browser language/timezone, or account region settings?
5. If my existing account is already region-flagged, is creating a new Meta account the only realistic option?

Any advice or working setups would be greatly appreciated. Thanks!
