@rjalex Sorry I didn’t reply earlier, must have missed your post. Yes, the app auto detects the device language and uses that, if possible. The language can permanently be changed in the settings menu (top right icon) under the mobile application settings, labeled language.
@Ramias I am not aware of this issue however I will look into it. Any specific error? Does the toggle jump back to off? Thanks.
Update: I think Windows Phone is caching the AJAX replies (no idea why any browser would cache AJAX). This is something Android 2.3 did however the same fix doesn’t apply to Windows Phone. I will try a few solutions and once one sticks I will push out a fix. Thanks for the report!
Update 2: I believe I found the solution and will be posting the fix soon.
