August 11, 2026
Reporting a scam link now works properly when the message uses a shortened link — CallWall follows it and blocks where it actually leads. Also fixed two cases where a scam link could be misread and reported incorrectly, and tightened what leaves your device when you report: only the link itself, never the message around it.
