If you have trouble with logging in, here are a few pointers on what you could do:
Make sure that your Shares app is updated. You can check this and update it in the Play Store if you are an android user, or in the App Store if you are an iPhone user.
After updating, you will be required to sign in again using your phone number. Just type in your phone number and log in using your previous login method.
If you still have trouble logging in, please contact our support team at support-team@shares.io.
