Just recently I noticed emails on Android phone (Samsung Galaxy S22 Ultra-US) are not synced with my newton mail app on MacBook Pro. Some emails do not show up on the MacBook version, although if I search for them it will find them somehow. They do disappear again when I clear the search, so basically they don’t show unless I search for them.
I love newton mail, been using it since 2014 but it is becoming a little sloppy and there is no support anymore while us as users still pay full price (gladly would continue paying if we get an actual support and a working app!)
Brotherly suggestion; either just shut the app down and get it over with or give it the minimum required to run a business.
