Research direction

Start by reproducing the issue in Android 16 with Push Fetch mode enabled and inspect the ADB logcat output and FETCH_PUSH_CONTENT broadcast behavior. Trace the Android notification fetch handling from the received intent, then verify that a push notification displays the sender name and message content instead of "Unknown" while older Android behavior remains intact.

Description

🐛 bug
Describe the Bug

On Android 16, the Rocket.Chat app shows push notifications in fetch mode as "Unknown". Users on older Android versions or other devices do not experience this issue.

Steps to Reproduce
  1. Install the Rocket.Chat app (latest version from Google Play)
  2. Go to Settings → Push → Enable “Fetch full message content on push receive”
  3. Send a Rocket.Chat push → notification shows only "Unknown"
  4. Disable fetch mode → name + message content appear correctly
Expected Behavior

Push notification should display name + message content, fetch mode works as intended

Actual Behavior

Push shows only "Unknown", fetch mode is blocked on Android 16

Rocket.Chat Server Version

OS Version

Android 16 (Stock)

Additional Context

ADB logcat for the notification:

NotificationRecord: pkg=chat.rocket.android user=UserHandle{0} id=<redacted> 
Notification(channel=rocketchatrn_channel_01, importance=4, visibility=PRIVATE)
StatusBarNotification: pkg=chat.rocket.android user=UserHandle{0} id=<redacted>
NotificationChannel: mId='rocketchatrn_channel_01', mName='All', mImportance=4

Manual fetch broadcast:

adb shell am broadcast -a chat.rocket.android.intent.action.FETCH_PUSH_CONTENT
Broadcasting: Intent { act=chat.rocket.android.intent.action.FETCH_PUSH_CONTENT }
Broadcast completed: result=0

Intent is received, but fetch does not execute
