Hello. Thanks for helping me in advance
Now, I am developing quiz app. Totally 5 push notifications should be delievered at designated time. Let's say,
1st quiz : 1pm / 2nd quiz : 2pm .. /5th quiz : 5pm
I set the above time and it is saved in firebase(scheduled time)
However, the main 2 problems are...
Sometimes, I got 3 push notifi , or sometimes 4 push notifi.
Once mobile is screen-off, push notifi is not delivered. As soon as I screen-on the device, then the push notifi delivers immediately
I'm wondering, it is device-side error. If yes, this matter will be very complicated... Or, do I need to use Firebase Cloud Messeging ?
Is there any developer who developed scheduled-time push notification app?
Thank you so much
