1) When trying to follow users, I get an error. The log says:
"Login failed: Failed to get session token."
So I logged in manually myself, and found that there's no problem at all with that account.
This is the most common error I have encountered when trying to perform actions.
2) When trying to repin:
"Error when repinning (username_here)-Error returned by Pinterest".
This is a different account from #1. Again when I logged in manually, it's fine. A board was already created previously so it's not a board error.
3) For error messages, usually no username is mentioned. This makes it hard to troubleshoot which account is potentially facing issues. For example, the error in #1 and also this error message: "Login Failed: Account is read only. failed to get email (Activation email not found)." In this particular case, it's very hard to find out which account requires me to go and trigger a resend of the activation email.
