Every time I sign in and use my email account I get blocked after a few minutes, a band appears across not allowing me to access my emails. It says I have to sign in again as I have not signed in for 24 hours or have signed into another account. It is getting very annoying as this never used to happen. It sometimes happens more than once in the same session and I have not accessed another account and have already signed in earlier in the day on another session. It does not make sense why this keeps happening. Has anyone any ideas please?
