notify on specific categoy

Hi, I’m trying to find a solution too. I found this guide,
https://www.ads-software.com/support/topic/category-wise-subscription/
it works only partially (for me), I can segment users using the suggested form, but I can not make selective submission work by category, when a specific post is published.
We hope someone can help us solve this problem.
However you can also consult the onesignal guide
https://documentation.onesignal.com/docs/web-push-wordpress-faq#section-how-do-i-categorize-users-and-send-notifications-to-specific-categories-of-users-

Thanks.

Hello

If you setup the segments and tags, we would suggest using our dashboard to send notifications so you can have more control over the message and users.

More on sending push notifications here: https://documentation.onesignal.com/docs/sending-notifications

While the plugin is nice to auto-send, if you are publishing a lot and want more control of your push, we would suggest taking advantage of our amazing dashboard or API if you want more control.
