emClient 10: Still very slow attachment loading

The new version unfortunately didn’t fix the (in my opinion) biggest flaw of emClint: the very very … continue for 8 minutes … very slow download of attachments.
Even a 2MB PDF File takes some minutes to download - in IOS mail, Outlook or Thunderbird it takes some seconds!
Please, please, please fix this! It is so annoying when you get an email with 4 plans each about 2-8MB in PDF or DWG Format and with emClient it’s like a coffee break after starting to download or preview attachments!

Hello,
what provider / email address are you experiencing it with?
Can you try enabling RAW download sync option on IMAP tab of your account?

And we would also like to see the IMAP logs if possible. We do quite a lot of heuristics to prevent this issue, but it seems there are still accounts/providers, where we are not successful with it.
