Email inbox: no more error message after a quarter of an hour
After about 15 minutes, the inbox reported “missing or invalid access token”. It now renews the sign-in itself, and the unread counter is correct immediately.
The problem
If you had the email inbox open for a longer time, after about a quarter of an hour every action produced the message “missing or invalid access token”. After reading, the sidebar still showed the old number of unread emails for up to a minute. And the submenu at “Messages” sometimes stayed open after a click.
The solution
The inbox renews the sign-in in the background and repeats the action without you noticing anything; the same applies to subscriptions and statistics. The number of unread emails in the sidebar updates as soon as you read an email. Submenus in the sidebar close immediately after a click.
