All applications in Windows that are using built-in Internet browsing controls (WebBrowse) will by default emulate Internet Explorer 7. I wrote about this ages ago but this post only targeted HTA scripts: https://deploywindows.info/2010/08/20/force-ie8-mode-in-hta/
Anyway while adding mobile Apps in the Configuration Manager Console it will bring up a WebBrowser control and head over to Google Play, Apple Store or Windows Store, and there are things that does not work with this control since it is emulating an old, very old, Internet Explorer.
So create a Group Policy (or just put it in your registry directly) and apply it to your computers with the ConfigMgr console for an improved browsing experience
The registry key is
Create a DWORD, either the first for emulating IE 10 OR the second for emulating IE 11
Microsoft.ConfigurationManagement.exe = (DWORD) 10000
Microsoft.ConfigurationManagement.exe = (DWORD) 11000
Make sure your registry key has applied and restart the ConfigMgr Console. This is how it looks afterwards, a little more interesting and the best of all? You can click the Apps in Google Play
