This app has been corrupted multiple times over the past year. First the Yahoo browser took over for Google chrome. It became the default browser (not good at all) and then had no technical support to put it back. Had to research the web to fix its. Now its calendar has been corrupted and sends phishing invitations to iphone calendars and again unsupported fix.There appears to be an uninvited calendar sys-ext-events$ that has been causing the problem. Have not found a way to delete or unfollow this at this time. You can delete it but it returns within a minute or two. Would never recommend anyone using this app or email.
