Sometimes when I delete an email is is not in trash - Gmail

Hi all,

Occasionally when I delete an email in emClient from a Gmail inbox folder the email is deleted but it does not go into the trash folder. When I log into Gmail online and search for the email it is nowhere to be found so it looks like emClient permenantly deleted it (just like I pressed Shift+Delete). How can this happen? I just deleted an email and now I need to retrieve it and I can’t. If I look in my trash folder I can see many emails that I deleted just fine from both emClient and from my phone but just occasionally emClient has a funny 5 minutes. I am on release 9.2.2093.

Thanks
Paul
