There could be 2 reasons
- The entered email is in fact not the one tied to your account. If you’ve shared a list with someone, ask them to tap “Share list” and then tap your name. On the details screen that appears, you can see the email we have for you in the system. If you spot a spelling error in your email, please contact support using the Send message button on our home page and describe the situation, then we can help you.
- The entered password is in fact not the one tied to your account. Tap the “Forgot password” button on the logon screen and request to get a reset password link from Grosh. The email should arrive within a minute or so. If this does not happen, look in your spam and commercial folders, especially Outlook has a habit of putting it there. If no mail arrives, it is an indication that the entered email is wrong, see no 1 above.
