NextCloud Talk notification is not work in android

I am new to Nextcloud. I have installed NC-18 on Centos-7. NC Talk installed and enabled in my NC server but I am not getting notification. Also installed the android NC Talk app in my android 10. Do I need to install any notification APP on my NC server? if yes how could I install it? I will be glad if someone helps me with this. Thanks in advance.

There is a notifications app in the default set of Nextcloud and it’s enabled by default.
Check if you disabled it by accident.

Otherwise note that only the GPlay installations of the android client.
Also you don’t get notifications when you have the conversation open on another device/browser.

Thanks for the reply. Problem solved with andoird client reinstall.
