Hi,
Just checking if anyone else is noticing FCM is having a delay in delivering the push notification or is it just me ?
I have a few customers saying push notifications being sent from my server have a delay. I started to think maybe it's my server having a issue sending the push notification, but everything looked normal.
Yesterday (and for the past few months) it been fairly instant and delivered to my iPhone & Android devices within 1-2 seconds.
Today I sent a test push notification from my computer (to rule out my server) when I send a test push notification using my computer (using the code below, which is the same as what I am using on my server), Google's server accepted the API call but the push notification didn't arrive for at least 20-30 seconds later. I then run the API command again, but the push notification arrived after around 1 minute. I ran it again and it was delivered within around 10-15 seconds.
I am using the following code, and not sure if anyone else is also noticing a delay of the FCM being delivered to the phone after the API has been processed ?
The delay is happening for both Android and iOS, and I tried while my phone is connected to WiFi and cellular 5G connection, but had the same result.
