FCM Topic Messages Delay

Hi!

I am using Firebase Cloud Messaging, and sending about 20 topic messages a day.

Unfortunately, some messages are delivered to devices with delay of several hours. It occurs often every day.

My topic messaging options are: priority is high, delay_while_idle is default(false).

In addition to that, I send notification messages to iOS devices and data messages to Android ones.

The delay of FCM occurs to everyone, or just my configuration is wrong?

Thanks,

Same here! It's happening since last Friday

I found that delays occur when I specify topic with "condition" key but not "to" key.

It's not the case in my situation. We set "to" field in the payload.

The exact behavior in my case:

1. send the push notification WITH TTL=3 hours

2. push notification delivered to small amount of users (~700)

3. several hours of delay (18-30 hrs and gets longer over time)

4. push notification delivered to the rest of the users (~ 100,000-200,000)

We can't work with FCM in current situation, especially when TTL is ignored.
