After Snapchat revisited QR codes, Facebook (naturally) also jumped on the QR code bandwagon, in a half-hearted manner, with QR style codes for their Messenger app.
Mashable thought they spotted a trend.
If they did, it was a short-lived one.
No one used the Facebook Messenger Codes on the Taza Control Panel.
Personally, I had one notable, related interaction. A tepid Facebook user, I had long ago deleted the Facebook Messenger app on my phone. But I reinstalled it to check that my new Messenger Codes worked.
In the process, I noticed a message from a friend I hadn't seen in awhile. So I responded.
His response: "Dude, I can't believe you just responded to a message I sent you THREE YEARS AGO!"
Sometime early in 2019, Facebook announced that they were sunsetting Facebook Messenger Codes in August, 2019.
