I did some testing on my Android mobile phone which has the latest OS and application software updates.
Links in Whatsapp, Emails, etc are being scanned, however, links in SMS text messages are not.
I confirmed this by watching the 'Scam Alert' page while testing. The 'Links scanned in texts, notifications, etc…..' did not increment up by +1, nor did any other counters when a link was received in an SMS / text message.
Is anyone else having this occur ? Alot of scams come thru SMS..
