WireGuard Windows 0.6.1 - Timeline of issues (tunnels lost & import still broken)

Hello,

I would like to report a clear timeline of issues observed with
WireGuard for Windows (version 0.6.1).

April 14:
- After updating, all existing tunnels disappeared
- Importing new tunnels failed
  - ZIP files were not visible
  - "*.*" filter did not help
  - Drag and drop did not work

April 16:
- Existing tunnels no longer disappear after update (possibly improved)
- However, importing new tunnels is still not working
  - ZIP files are still not visible in the import dialog
  - "*.*" filter does not work
  - Drag and drop still fails

At this point:
- It is unclear whether the tunnel disappearance issue is fully fixed or not
- The import issue remains critical and consistently reproducible

Impact:
- Users cannot add new tunnels after installation or update
- This is affecting a production VPN service with multiple users

Please confirm:
- Whether there was a recent change in the update package
- Whether the import issue is a known bug
- When a fix can be expected

Thank you.
