Messages on the server are only downloading to eM client on PC and not my iphone

I leave eM client running in the background on my PC. Why are messages on the server only downloading to eM client and not my iphone email client?
I’m on IMAP.

Hello Timekeeper,

Thank you for reporting this.
However, if your emails download correctly to your PC and you can see them on the server, I’d recommend contacting the provider of your phone app.
