Continuation of #3409 — Group DM notifications are not grouped and every message plays a notification sound

(#3439) Bug Needs triage mobile

Observed behaviour

The issue from #1762 is still reproducible. Every message arriving in the Group DM is treated as a separate notification instead of being grouped/stacked. Each notification also plays the notification sound(the recording doesn't pick up the sound but check the ring icon next to the notification, that is the phone playing the sound), causing the phone to repeatedly ring for every message. A screen recording demonstrating the issue is attached.

Reproduction steps

  1. Open a Group DM in the Fluxer mobile app.
  2. Have multiple messages arrive in the Group DM within a short period of time.
  3. Observe the notifications received by the phone.

Details

Expected behaviour Multiple messages from the same Group DM should be grouped/stacked into a single notification rather than each message creating a separate notification. The notification sound should also not play repeatedly for every individual message in rapid succession.

Can reproduce CR - Notifications were properly grouped, but each triggered a notification sound individually despite rapid-firing several messages in a row. Three separate trials returned the same results.
