Gain Coin — Account Support
If you got a "This device is already linked" error when trying to log in, fill out this form. This issue typically occurs if you get a new phone, reinstall the app, or use multiple Google accounts on the same device. Our admin will review your request and reset your device within 24–48 hours.
IMPORTANT — Before You Submit
Make sure the Gmail account you enter below is the exact same Gmail that you used to sign in to the Gain Coin app.
If you signed in with one Gmail in the app but type a different Gmail here, your request will fail automatically.
Open the Gain Coin app and try to log in with Google.
You will see a red/blue error message at the bottom of the login screen.
Tap the "Copy" button next to your Device ID.
Paste it in the Device ID field below and submit this form.
Your device reset request has been received. Our admin will review and reset your device within 24–48 hours. Please check the app again after that time.
