If the verification can't be successfully reached your side, there are following possibilities:

1. The account may be not within the right format, maybe you can try another account and try again.
2. The e-mail with verification may have been put in your junk inbox, maybe you can double check it.

If the tips can't work, pls register with another E-mail and try again .

You may also try to login via strava ID or apple account directly.

Note: iGPSPORT recommends you enter the verification code within 30 minutes as the valid time is 30 minutes.
