[Bug]: iOS Live Activity compact status text wraps onto two lines when another Live Activity shares the Dynamic Island #15682
Description
Before submitting
- I searched existing issues and did not find a duplicate.
- I included enough detail to reproduce or investigate the problem.
Area
apps/mobile
Steps to reproduce
- Enable Live Activities in the T3 Code iOS app and start an agent turn so the
AgentActivityLive Activity appears. - Start a Live Activity from any other app (e.g. a podcast/now-playing, timer, or sports activity) so the Dynamic Island shows two activities side by side.
- Look at the T3 pill while the agent is running ("1 active"), then again after it finishes ("Done").
Expected behavior
The compact trailing status stays on one line, e.g. T3 1 active / T3 Done. If space is tight, it should shrink or fall back to a shorter form, not break across lines.
Actual behavior
The compact trailing label wraps onto a second line:
1 activeshows as1aboveact…Donebreaks in the middle of the word, asDonabovee
The T3 pill still has plenty of empty horizontal space, so the label is wrapping inside a narrow trailing slot, not because the pill is full.
Likely cause
apps/mobile/src/widgets/AgentActivity.tsx (main @ 4ee6bfd), compactTrailing:
compactTrailing: (
<Text modifiers={[font({ weight: "semibold", size: 11 }), foregroundStyle(tint)]}>
{attentionRow
? attentionRow.phase === "waiting_for_approval"
? "Approval"
: "Input"
: activeLabel}
</Text>
),This is the only status Text in the file without lineLimit(1); the banner, watch card, and row texts all have it. When iOS gives the trailing region a narrow proposed width (as it does when the island is shared), SwiftUI wraps the text instead of truncating it.
Suggested fix
- Add
lineLimit(1)to thecompactTrailingtext, plusminimumScaleFactor(...)orfixedSize()so it shrinks or takes its natural width instead of truncating or wrapping. - Optionally use a terser compact label: the count only (
1) while running, and the existing phase glyph (checkmark / cross) for Done/Failed, matching whatminimalalready does.Approval/Input/Out of datecan hit the same problem.
Impact
Cosmetic issue
Version or commit
T3 Code iOS 2.0.0; code reference main @ 4ee6bfd
Environment
iPhone 18 Pro Max, iOS 27.2. Reproduced whenever a second app's Live Activity shares the Dynamic Island.
Screenshots
Running — 1 active wraps to 1 / act… (the other app's activity is blurred):
Finished — Done breaks as Don / e:

Triage
Thanks for the report and the clear screenshots, @jlipworth. The shared-island repro was enough to pin this down.
What I found
Confirmed on

Those sit in wider stacks, though, and aren't the pill in your screenshots.Likely fix area
Options for
compactTrailing, using modifiers@expo/uialready provides (fixedSizeis used inSubscriptionUsage.tsx):fixedSize({ horizontal: true, vertical: false }), so the label takes its natural width.lineLimit(1), so a label that still doesn't fit stays on one line and truncates.minimumScaleFactoron its own would shrink the text to fit the narrow slot and leave the empty space unused. It would mainly help longer labels likeOut of dateorApproval.AgentActivity.test.tschecks the compact strings but not line breaking, so the wrap would need checking on a device with a second Live Activity running. This code is built into the widget extension, so any fix ships with a new iOS build.A maintainer will decide on the fix direction.

Submitted #23035 for this compact-layout defect.
The fix keeps status labels such as Input and Approval on one line and shows running work as a bold black count inside a filled circle, capped at 99+. The native accessibility label retains the actual total.
The PR shows the original bug beside the final design, including the final 99+ case, with a continuous six-second native recording at 30 fps. It also includes final native accessibility results, focused check output, and disposable reproduction fixtures. The evidence uses an actual second Live Activity on an iPhone 18 Pro simulator running iOS 27.0. All media are status-bar crops reviewed for personal information.
The native build and pre-push checks passed. Physical iOS 27.0.1, single-activity visual behavior, VoiceOver speech, relay/APNs delivery, and the stale Out of date presentation remain unverified.
fix(mobile): keep compact Dynamic Island status readable
fix(mobile): Dynamic Island status no longer wraps next to other Live…
chore: merge latest upstream main into develop (#3)
