yes there is no problem for this notification. When you click on the notification, you enter the adalo application, but there is no screen to answer the call. @Victor
Based on this I think that the problem might be specific to your app. I would recommend submitting a ticket. There is a small probability that something could be broken in the latest build process (my app was built some time ago), but anyway, only someone with the access to Adalo servers (read: Adalo employee) can diagnose the problem.
@Dilon you can test the notifications when you make a native build of your app.
So the answer is “Yes”. Please check here how to make a native build: Publishing to the Google Play Store - Adalo Resources
You don’t need to publish the actual app, of course.
