Hi there! I see you're having trouble sending a reply to an interested buyer on VarageSale. To help you better, could you tell me if you're using the VarageSale app or the website? Also, are you getting any specific error message or does the message just not send?

In the meantime, here’s a general step-by-step guide to troubleshoot this issue on your Android device:

1. Check Your Internet Connection: Make sure you have a stable internet connection, either Wi-Fi or mobile data.

2. Restart the App: Close the VarageSale app completely and reopen it. Sometimes, this refresh helps messages go through.

3. Update the App: Ensure that you have the latest version of the VarageSale app installed from the Google Play Store.

4. Clear Cache: On your Android 10 device, go to Settings > Apps > VarageSale > Storage > Clear Cache. This can fix temporary glitches.

5. Check Blocked Users: Verify that you or the buyer haven’t accidentally blocked each other, which would prevent messaging.

6. Try Messaging Through the Profile: Instead of replying through the "interested" notification, try tapping the buyer’s profile and hitting the “Message” button directly to compose a new message1.

7. Log Out and Back In: Sometimes re-authenticating your account can resolve minor issues.

If after trying these you still can’t send a reply, please let me know what happened after each step. We can then explore deeper settings or check if there’s a server-wide issue or account-specific problem.

Are you satisfied with the solution I provided so far?
