Sync read email in iphone vs Imap client

I use emclient with imap and sync with my iphone, when I read an email on the iphone, it does not mark as read in emclient
Solve emclient are closing and opening, if I do the opposite works
im use the last version

Hi, it is not immediate you have to wait until eM client will synchronize with server and get information about read status.

Try reading some message in your iPhone, then wait a few seconds until iPhone will information about message status to the mail server and then in eM Client click on send & receive, that should force synchronization with server.
