Currently running some Unifi AP's with the promotional url being used as a landing page. Working great on iOS but on Android and Windows Phone it seems to show up but then it disappears after 1 second.
It seems to stay open with older versions of Android so I am thinking its something to do within Android itself.
Just wondering if anybody had any workarounds or ideas to stop it disappearing?
Had a search in the Unifi forums but only found a topic describing the same issue without any solutions that seems to work (https://community.ubnt.com/t5/UniFi-Wireless/Promotional-URL-not-working-on-Windows-Phone-and-Android/td-p/1190015).
