If you've changed your Pinterest password, you need to reconnect your Pinterest Profile with Viraltag. This will fix any issues you are facing with scheduling content.
To reconnect your Pinterest profile, go to the 'Accounts' section, and under the 'Profiles Connected' list you'll see text in red next to your Pinterest profile icon.
It reads 'The token has expired. Click here to reconnect this account'. Clicking on this will redirect you to the Authorization page. Following this, enter your Pinterest Credentials and you're good to go!
