Very disappointed about the Conversations setting

I like the Conversation setting of eM Client, but must now conclude this setting is completely unreliable with my service provider, so I have to disable this viewing of my emails.
Otherwise emails vanished, and I have to force eM Client to refresh the folder to get the emails back again in the viewer!
This is completely unacceptable, and I now have to consider to change to another email client that live up to my requirements!

Who is your service provider ?

Also what version of eM Client are you using ?
