Not Receiving Push notifications - IOS

I am trying to send Push notifications for backendless console, I only receive push notification if select the selected device option and select my device.
I want to receive push notification if I select IOS devices or is there any way to select all the devices from console because I my app has 1000s of users

Thanks

Hi, Ammar.
On the “Messaging” tab -> “Devices” you should see “Send push notification” at the bottom of the screen. Here you can choose Android or iOS. If you do not choose any particular device from list above, the message should be send to all registered devices. Pay attention, if you have a lot of registered devices, message sending can take time.

It is work for you ?

Ok, thanks but I the issue is push does not come every time, second how long will it take to send push to 1500 users ?

What you mean, when say " I the issue is push does not come every time" ? You send push to some device and it didn’t come every time you press send button?
About the second question: I can not say exact time, because it depends on how fast apple server can receive all notification from our server.

Yes this is what I exactly meant to say, but now I have checked push is working fine.

Thanks for quick response. Backendless has made my life so easy
Thank you.
