didn't get Pusher related data

We've installed the Synapse server in an OVH VPS server. But got push related issue.
When I logged in via the play store's element app, everything works fine. Got the pusher data in the server completely.

**`@junayed:priyo.net im.vector.app.android Element (Riot.im) er7LNlDSQTq1y6df_BGgJ8:APA91bEofKWPPnUJmDUDL {"format":"event_id_only","url":"https://matrix.org/_matrix/push/v1/notify"}`**

But if I logged in via APK built from source code, no pusher related data is sent to the Synapse server. I guess, in the custom APK, those parts of code didn't execute for some unknown reason. However, Messaging, call, etc works fine in the custom APK. So I'm confused about what I'm missing.

I've used the latest version 1.0.5.
Device: One plus 6
Android: 10

Can you help me giving some guidelines?
Thanks in advance.
