Glide Push Notifications not working on Android

Is it only me or is everyone else facing issue with the Glide Push Notifications?

I believe that I have set everything right and it is working fine on the Desktop but I am not able to get the notifications on my Android device even though I had installed the app on my home screen as it was mentioned in the Documents and the weirdest thing is after installing the app in my Android and after giving the notification permission when I clicked on the send button, it sends me the notification on my Desktop even though I am making request on my Android device and I am also not logged-in on the desktopšŸ˜¬

Any suggestions/recommendations on this?

App Link if you want to try: qasimnof.glide.page
Anyone can login though email or Gmail
