When Trello stopped supporting Internet Explorer, my team all downloaded Chrome so we could carry on using Trello.
Unfortunately, as our organisation continues to use Explorer as our default browser, we can no longer use the links in any email notifications, as our system automatically attempts to open them in Internet Explorer.
Delving around Trello and Outlook we can find no way to get the links to open Chrome instead of Explorer.
Has anyone found a work around for this?
