Not really.. I haven't set up push-notifications yet. I probably won't do it at all. I meant those small red bubbles that contain the number of new messages/notifications and pop-up in the right corner of the messenger sign, profile sign or notification sign. I have them on the web-site, but I don't have them in my apps for some reason. I checked the UNA.IO app and it has these notifications. I didn't change the App.js file much - only the colors and I deactivated the Add new content button (+).  

Please check if you have these in items in Notifications Menu, if you remove these items from Notifications menu then notification for this item will not work in mobile app. If you want this item invisible on your site in notifications menu, then you can hide it like this:
