If you're encountering an 'invalid EVC' error when trying to e-verify an updated Income Tax return, it might be due to a timing issue. The suggested solution is to delete any previous e-verification attempts from your mobile device and then resend and submit the EVC. This should resolve the problem and allow for successful verification.
