If you are unable to receive Email OTP on your registered email address, then maybe your internet speed is unstable or slow. Please check whether your inbox is full and if you are receiving emails from other service providers. If you're using Wi-Fi, try to switch to mobile data, and vice-versa.
Please follow these simple steps to sort the issue.
1. In case you are using mobile data, turn ON and OFF the airplane mode on your phone.
2. Update your CoinSwitch mobile app to its latest version on Play Store/App Store.
3. Uninstall and reinstall your CoinSwitch mobile app.
Note: For security reasons, in a span of 12 hours, you can generate a maximum of 6 OTPs. If you've exceeded this limit, you will be unable to generate a new OTP for 12 hours.
