Hi! I understand you're not receiving text notifications for assignments from the Red Rover K12 app on your iPhone running iOS 18.6.2. Let's get to the bottom of this.

First, could you tell me if you’re currently using the Red Rover mobile app for your assignments, or are you expecting notifications strictly via SMS text messages? Also, have you made any recent changes like uninstalling the app, changing your phone number, or texting STOP to the service?

This info will help me guide you better. Meanwhile, here are some common checks we can start with:

1. Check Notification Settings in Red Rover:
- Open the Red Rover app.
- Tap your profile icon or name (usually top right).
- Go to Settings > Notifications.
- Ensure the option for receiving text message notifications (for assignments) is enabled.

2. Verify Text Message Subscription:
Sometimes, if you text STOP to the Red Rover number, text notifications pause. If you suspect this:
- Try texting START or HELP to the Red Rover text number to resume messages.

3. Review iPhone Message Settings:
- Open Settings on your iPhone.
- Go to Notifications > Messages.
- Make sure notifications are allowed, and styles like banners or alerts are enabled for texts.

4. If Using the App and Text Notifications Both:
The system might prioritize app notifications over text. Some users find that uninstalling the app resumes text messages for assignments if preferred.

5. Check Network Connection:
Ensure your iPhone has a stable cellular connection to receive texts.

If after these steps the issue persists, it may be helpful to contact your school district administrator or staffing agency since they manage your profile on Red Rover. Sometimes account or system settings on their end can affect notifications.

Would you like me to guide you step-by-step through these checks? Also, please share if you noticed anything unusual or any error messages so far.
