Synchronization Android app

If I open an e-mail on the computer in the desktop eM Client, mark it with a Label and click Archive, the action is performed on the computer, but not on the phone. And that’s even after manually syncing by swiping. It is necessary to do both actions that I did on the computer, on the phone😒. Sometimes, however, it is enough to open the relevant Label folder and then synchronization will occur.

I get this as well and in particular when using the snooze function - have tried getting to the bottom of it months ago but no joy
