If you’re heading out to Mobile World Congress, you can pick up the latest edition of our print magazine in any of the Networking Lounges around the show. But if you can’t wait that long, you can read the issue online now.

There’s a ton of great content inside, including an in-depth look at one of the biggest issue facing the ad tech industry right now – transparency. We also take a look at ad fraud, with an ads.txt 101 explainer, and assess the challenges facing the social networks of late. And that’s before Snap had $1.6bn wiped off its valuation after one fairly innocuous tweet. Fickle types these social media users!

Elsewhere in the issue, Hostelworld’s Breffni Horgan walks us through the companys mobile strategy, and in particular, how it has worked to make its app so much more than just a booking platform. Tune’s Chris O’Shea offers advice on how to engage with app users post-app install. And we stay with apps as YouAppi founder Moshe Vaknin explains his company’s approach to finding and retaining app users.

On top of all this, we have Code Computerlove and Tealium on personalisation; Weve on customer engagement; SAP Digital Interconnect on IoT connectivity and multichannel messaging; Digital Element on IP geolocation; SpotX on OTT video; Sizmek on AI-powered advertising; and Research now SSI on the value of data.
