However, if it will take some time (couple of days) to display the stats.
Please make sure to upgrade to the latest ST mobile app versions (v2.2.3/2.2.4) on Android (especially)… I don’t know what is your phone or tablet OS (Android or iOS)… Android requires the latest version of the ST mobile app for the HTMLtile to work properly.
If you have any other ST mobile app version or OS (e.g. Windows mobile), I cannot guarantee that it will work.
