Hello I’ve been using this app for years and it has been good until recently. It has stopped syncing with the email server. On the desktop and on my husbands phone it still works fine. Emails eventually come in if I reset the phone but it is still not showing that as of yesterday‘s emails. For example I deleted a whole bunch of emails and they are all still showing and the sync icon is just spinning. Please help. 

I have an iPhone 7
