An email momentarily appears in my iPad inbox and instantly disappears from it leaving it blank.
The inbox is @me.com which is the same as mac.com.
It also is present on my desktop MAC which may be a factor. But the emails remain on my desktop. Why not on my iPad.
Please if you reply to forum send a copy to gedeon_hATmeDOTcom - this an email address which I can not write properly as this will not send if I do so please write it properly when you use it. Note the underscore_between the n and h in my name.
