Hi there! I see you're having trouble with the Skinape app showing a "username not found" error when you enter your Roblox username. Let's try to get this sorted out together.

First, can I ask:
- Are you entering your exact Roblox username, including correct capitalization and spacing?
- Have you recently changed your Roblox username or display name?
- Are you able to log into Roblox directly with that username?

Sometimes, Skinape might not recognize usernames if there’s a mismatch or if the account is new or recently renamed.

Here’s a step-by-step approach to try:

1. Double-check username spelling: Make sure you’re entering your Roblox username exactly as it appears on Roblox, including capitalization. Skinape might be case-sensitive.

2. Verify your Roblox account status: Log into Roblox itself to confirm your username is active and spelled as you think.

3. Restart the Skinape app: Close and reopen Skinape to refresh its user data.

4. Clear Skinape's cache on your Android device:
- Go to Settings > Apps > Skinape
- Tap Storage > Clear Cache
- Then try entering your username again.

5. Update Skinape app: Make sure your Skinape app is updated to the latest version from the Google Play Store.

6. Check for account linking guidance: Sometimes, Skinape requires linking your Roblox account properly via their interface or website. Look for any option in Skinape to “Connect Roblox account” and follow prompts carefully.

If you still get the “user not found” error after these steps, it could relate to a temporary syncing issue between Skinape and Roblox’s servers, or Skinape’s system might have trouble retrieving data for some accounts.

Would you like me to help you verify your Roblox username or check Skinape’s support channels for any ongoing issues affecting account recognition?

Let me know, and we can take the next steps from there! Are you able to try these steps now?
