Claude Code mobile: session list frozen, new/updated sessions never appear

Environment

• Claude Code mobile app ("Code"), iOS (app version not confirmed — no update available in App Store as of today)
• Companion desktop: Claude Code CLI on macOS

Summary
The Sessions list in the mobile app is stuck on a stale snapshot. Sessions created or updated within roughly the last 24 hours never appear in the list, while the same handful of days-old entries persist unchanged across repeated checks.

Observed

1. On the desktop, several Claude Code sessions were created/active today (e.g. titled "Max v6", "Corinne (OtJ) v16", "Corinne (OtJ) v16 (fork)", "Network School fellowship application", and a merged-PR session "Meadowes authorization review").
2. None of these appear in the mobile app's session list.
3. The list instead still shows older sessions unchanged — e.g. "Corinne (OtJ) v15", "Max v4", "Battleship v4" all still marked "4d" ago, "Meadowes connector memo" / "Review handoff document..." still "Aug 6", "Biblebob daily" still "Aug 5" — identical across two checks taken 8 minutes apart.
4. Only the one session currently actively streaming to the phone updates live (shows "Connected" / "now").

Isolating the bug
Confirmed server-side that one of the "missing" sessions ("Max v6") was genuinely alive: sending it a message via Claude Code's own session-management tools caused its underlying process to start running again (its isRunning state flipped to true, confirmed via the desktop's process list too). Despite being demonstrably alive and active, it still never appeared in the mobile session list.

This points to the bug living in the mobile client's session-list sync/fetch/render path, not in backend session state.

Troubleshooting already tried — none resolved it

• Force-quit and reopened the app
• Checked the "All" sessions filter dropdown for a hidden device/workspace scope
• Logged out and back in (full re-authentication)
• Checked the App Store for an update (none available)
• Toggled Airplane Mode / forced a full network reconnect

Expected behavior
The session list should reflect all sessions on the account, and should refresh at minimum after a full logout/login.

Actual behavior
The list stays frozen on an old snapshot indefinitely; new or updated sessions never surface despite exhausting standard cache-busting steps.
