Mail App shows email coming in then it disappears
I'm running the latest Mac mail app for my .mac email account and for the last two days when ever new emails come in they immediately disappear, so the ping goes off that its arrived and I can see it is in but then it disappears ? it is doing it on all my mail app's across devices so on my macbook, iMac, iPad and iPhone
is there any way to reset and start again as I am basically not seeing any new emails for my main email account 😟
