Pop ups while writing text msg

[Mike Manwell]

Just recently, while writing a text, a pop up ad appears. Some are adds are on subjects I've never expressed interest in.
Any suggestions?
Thanks in advance

What messaging app do you use? It might be coming from there.

Otherwise, did it start after installing a specific app?

I get a ton of junk email. Nothing is more irritating when you're showing pictures on your phone to a colleague at work and get a pop up email notification advertising some pornographic service. I still can't believe that there isn't a way of turning pop up notifications off.
