Hallo,
vielen Dank für das tolle Update von emClient für ios und ipadOs.
Mails und der Kalender werden gut synchronisiert.
Leider fehlt aber bei den E-Mails die Synchronisation der Suchordner.
Das wäre doch ein prima Weihnachtsgeschenk, oder? 
Viele Grüße
Andreas
thank you very much for the great update of emClient for iOS and iPadOS.
Emails and the calendar are synchronized well. Unfortunately, the search folders
are missing from the emails.
When you click the magnifying glass “Search” icon at the top of the mobile app, you can then click on the “Options” button to select your search folders eg: All Folders, Current Folder and sub folders or Custom folders etc,
You can also click the “Advanced” button in Search to create custom “Search folders” and add search fields at the bottom to permanently bring up those search results on the left of eM Client.
“Search Options” Android example
“Advanced Search” Android example
I think, you don’t know what I mean. On your last screenshot (advanced search), there is the possibility to “Create Search Folder”. And those created Search folders will not be sync over all devices. Am I right? 
Yes as far as I’m aware, you have to create those search folders “on each device as they are not server based” and only local to each device.
If that’s not correct someone will update this thread.
Yes, that’s correct, but you can do one-time export and import of them via QR code
