Which plugin are you using for push notifications? Did you check its readme to see if it works for Windows Phone?
(Thank you for creating separate threads for different issues!)
The plugin is right and works for Windows Phone, iOS and Android.
The company OneSignal suggests to install the plugin for proper operation:
The plugin is as follows:
This plugin works perfectly with Android. But for some reason you are not getting push notifications for Windows Phone.
The support of the company OneSignal asked me to consult with you
Based on my research for that preference (<preference name = "WindowsToastCapable" value = "true" />) it may be that it only works with the "windows" target and not the "windows8" target.
Are you able to try this experiment using a Windows 10 device and the Windows UAP build?
My device for testing is Windows Phone 8.1.
I added this line: <preference name="windows-target-version" value="8.1" /> and <preference name="WindowsToastCapable" value="true" /> into the file intelxdk.config.additions.xml
I build on Windows Phone 8.1
next I installed the app into my WP8.1
but the same thing happened again. The registration functioned, but when I sent a push notification the phone didn't receive it.
And next the device is unsubscribed on OneSignal
I do not know what else to do...
Thank you everyone for your help.
Finally the problem has been resolved, in part, because of the links and help you have given me.
I only needed to enter thess lines on the bottom of the file intelxdk.config.additions.xml
<preference name="windows-target-version" value="8.1" />
<preference name="WindowsToastCapable" value="true" />
