iPhone apps store content display problem

Hi all

I am experiencing display issues on the apps store on the iPhone only. I'm on 6.1.3 and I don't have the issue on iPad.

Text is overlapping with pictures and descriptions. It really does look like a mess. Button "buy" or "Free" are enormous. This is impossible to browse properly. I have screenshots to share.

It is happening for the past 2 weeks now and I thought it was an apple server problem but it persists. I have erased network settings and also all settings. Not content and settings. I don't want to have to do a restore as new just for that.

Any ideas what to do?
