Hi there! I see you're having trouble sending or receiving files between your ibis Paint app and your friend's Discord on your Android device. Let's see if we can get that sorted out together.

To understand better:
- Are you trying to share your ibis Paint artwork files (like the project file or image exports) through Discord?
- Do you get any error messages when you try to send files?
- Is this issue happening with all file types or only specific ones exported from ibis Paint?
- Also, is your Discord app up to date and working fine otherwise?

This info will help me guide you precisely.

Meanwhile, here are some basic steps to troubleshoot file sharing between ibis Paint and Discord on your Android (WebKit) device with Android 10:

1. Check file format and size:
Discord has limits — typically, files must be under 8MB unless you have Discord Nitro. Make sure your ibis Paint saves (PNG or JPEG images) fit under this size limit.

2. Use the Share option inside ibis Paint:
Try opening your artwork in ibis Paint, then tap and hold the file or tap the share icon. Select Discord from the share menu to send the image directly rather than sending it from within Discord. This often solves compatibility issues.

3. Allow Discord permissions:
Make sure Discord has storage permissions enabled on your Android system. Go to Settings > Apps > Discord > Permissions and make sure storage permission is granted so the app can access files.

4. Check network connection:
Sometimes file sending can fail if the connection is unstable. Try switching between Wi-Fi and mobile data to test.

5. Restart your apps:
Close both ibis Paint and Discord fully (from recent apps list) and reopen. Sometimes background glitches can cause file sharing to fail.

If you've tried all these and still facing trouble, let me know what exactly happens when you try to send or receive the file. I can guide you through more advanced troubleshooting from there.

Are you able to try these steps and share what you observe?
