### **Bug Report: Missing Timestamp in Gotify Notifications on HyperOS (Redmi K70 Ultra)**

#### **Environment**
- **Device**: Redmi K70 Ultra
- **OS**: HyperOS 2.0
- **Gotify Version**: Android Client v2.8.1 / Server v2.6.1 (example)
- **Reproducibility**: Consistent

#### **Description**
On **Redmi K70 Ultra (HyperOS 2.0)**, Gotify notifications **only display the timestamp** when the message contains line breaks (`\n`). Single-line messages show no timestamp, reducing usability for brief alerts.

#### **Steps to Reproduce**
1. **Send a single-line message via Gotify API**:
```bash
curl "http://gotify-server/message?token=XXX" -F "message=Test message" -F "priority=5"
```
→ **No timestamp appears** in the notification.

2. **Send a multi-line message**:
```bash
curl "http://gotify-server/message?token=XXX" -F "message=Line 1\nLine 2" -F "priority=5"
```
→ **Timestamp is displayed** (e.g., "19:45").

#### **Expected Behavior**
- Timestamp should appear **regardless of line breaks**.

#### **Actual Behavior**
- **Single-line messages** → **No timestamp**
- **Multi-line messages** → **Timestamp visible**

#### **Possible Cause**
HyperOS may apply different notification templates based on message length/formatting, causing Gotify’s timestamp to be hidden in single-line notifications.

#### **Workaround**
Manually add a line break (`\n`) to force timestamp visibility:
```bash
curl "http://gotify-server/message?token=XXX" -F "message=Alert\n" -F "priority=5"
```

#### **Additional Notes**
- Issue persists across reboots & reinstalls.
- Other Xiaomi/HyperOS devices may be affected.

Would appreciate any insights or fixes from the Gotify/HyperOS teams. Thanks!
