Android app: Long-press message action sheet intermittently fails after scrolling in active channels

Description:

When long-pressing a message in the Android app, the message highlight animation plays correctly (gray background expands across the screen), indicating the gesture is detected. However, the message action sheet/modal does not appear consistently.

This occurs most frequently after scrolling back in active channels.

The issue is intermittent. Repeating the long-press often eventually succeeds.

Steps to reproduce:

1. Open a high-activity channel with many messages.
2. Scroll upward to older messages.
3. Long-press an older message.
4. Observe that:

• Highlight animation plays
• Action sheet often does not appear.

5. Repeat long-press; it may succeed after multiple attempts.

Expected behavior:

After a successful long-press:

• Message highlight animation completes
• Message action sheet opens reliably
• User can react, reply in thread, quote, etc.

Actual behavior:

• Long-press is detected (highlight animation plays)
• Gray selection background expands fully
• Background disappears
• No action sheet is shown
• Repeating the long-press sometimes eventually works

Server Setup Information:

• Rocket.Chat Server: 7.13.3 (Docker)
• Android App: 4.70.0.108308 (also observed on February release)
• Android version: 15
• Dark mode enabled (issue observed there)
• Occurs primarily in high-activity channels with long message history

Additional context

• Issue is more common in channels with heavy message history.
• Appears related to message list virtualization.
• Does not occur in the web client.
• Server appears unaffected (other message interactions work normally).
• No server-side errors observed.
• Suggests client-side modal/navigation timing issue.

Suspected Area

Possibly related to:

• React Native FlatList message recycling
• Long-press gesture handler timing
• Modal/bottom sheet presentation race condition
• Navigation stack interaction after scroll
• Animation completion callback

Impact

High usability impact for active teams.
Users rely heavily on long-press actions for:

• Reactions
• Thread replies
• Quoting
• Message context actions

Start by reproducing the long-press flow in the Android app using a high-activity channel, then trace the React Native FlatList message recycling, gesture handler, and modal or bottom-sheet presentation after scrolling. Compare the animation completion and navigation timing; done means the action sheet opens reliably for older messages and exposes the expected message actions.
