Hi there! I understand you're experiencing an issue where Quiver shows a solid block of red. That can be frustrating! Let's work together to get this figured out.

First, could you let me know if you've tried any troubleshooting steps already? For instance, have you checked the app permissions or tried restarting the app?

If you haven't done that yet, here are some steps to start with:

1. Check App Permissions:
- Go to Settings on your Android device.
- Scroll down and select Apps.
- Find and select Quiver.
- Check if all the necessary permissions are enabled. Sometimes, missing permissions can lead to display issues.

2. Restart the App:
- Close Quiver completely and reopen it to see if the issue persists.

3. Clear Cache:
- In the same app settings, you should see an option to Storage.
- Here, you can clear the cache. After that, try reopening Quiver.

If you’ve already tried these steps and nothing seems to change, let me know, and we can dig deeper into this!
