To Reproduce

1. Connect to the internet via any ISP in Mainland China (without VPN/proxy).
2. Attempt to open the Raindrop.io web app, sync via the browser extension, or use the mobile app.
3. Cannot connect / Cannot update.

Web bookmarks can be saved and updated normally in Mainland China.

Environment:

• Location: Mainland China
• ISP: [China Telecom / China Unicom / China Mobile]

Additional context
Are there any plans to optimize CDN nodes for mainland users, or perhaps provide an alternative API domain that might survive the local network weather? Any workarounds would be hugely appreciated by your mainland Chinese user base!
